Answer:
isosceles trapezoid
Step-by-step explanation:
1) find the distance of the points
[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex]
AB = [tex]\sqrt{(4-2)^2 + (7-5)^2} = \sqrt{4 + 4} = \sqrt{8} = 2 \sqrt{2}[/tex]
BC = |7-4| = 3
CD = [tex]\sqrt{(9-7)^2 + (5-7)^2}= \sqrt{4+4} = \sqrt{8} = 2 \sqrt{2}[/tex]
AD = |9-2| = 7
2) equation of the line that passes threw BC
y = 7
3) equation of the line that passes threw AD
y = 5
conclusion
the quadrilateral has two parallel sides and two congruent sides, so it is a isosceles trapezoid

A student needs 15 minutes to solve an algebra problem. How many minutes does the student need to solve 5 problems?
it's easy, you only need to divide 15 by 5.
Like this :
15÷5= 3
• because 5×3 = 15 , so you just need to flip it over
so, the student need 3 minutes to solve 5 problems

What is the radius of the circle?
Answer:
8×ED=3×15
ED=45/8
the radius is the half of the diameter

Find the hypotenuse of a right triangle if the legs are 22 and 26. Round to nearest hundredth
Answer:
Step-by-step explanation:
length of Legs of the right angle triangle = 22 (unit) and 26 (unit)
To find the length of hypotenuse of the right angle triangle, we have to use Pythagoras property
Lets keep hypotenuse as "h" and one leg as "a" and another as "b"
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]h^{2}[/tex]
[tex]22^{2}[/tex] + [tex]26^{2}[/tex] = [tex]h^{2}[/tex]
484 + 676 = [tex]h^{2}[/tex]
[tex]h^{2}[/tex] = 1,160
h = [tex]\sqrt{1,160}[/tex]
h = 34.05 (unit)
Find the value of x in the triangle shown below

HELPPPP
please help me answer this question-
Answer:
[tex] \displaystyle GH = 2 \sqrt{30} [/tex]
[tex] \displaystyle FH = 2 \sqrt{10} [/tex]
[tex] \displaystyle m \angle G = {30}^{ \circ} [/tex]
Step-by-step explanation:
QUESTION-2:we are given a right angle triangle
it's a 30-60-90 triangle of which FH is the shortest side
remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus
our equation is
[tex] \displaystyle 2FH=4\sqrt{10}[/tex]
divide both sides by 2
[tex] \displaystyle\frac{2FH}{2}= \frac{ 4 \sqrt{10} }{2}[/tex]
[tex] \displaystyle FH =2 \sqrt{10}[/tex]
Question-1:in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle
as we want to figure out GH we'll use sin function
remember that,
[tex] \displaystyle \sin( \theta) = \frac{opp}{hypo} [/tex]
let our opp, hypo and [tex]\theta[/tex] be GH, 4√10 and 60° respectively
thus substitute:
[tex] \displaystyle \sin( {60}^{ \circ} ) = \frac{GH}{4 \sqrt{10} } [/tex]
recall unit circle:
[tex] \displaystyle \frac{ \sqrt{3} }{2} = \frac{GH}{4 \sqrt{10} } [/tex]
cross multiplication:
[tex] \displaystyle 2 GH = 4 \sqrt{10} \times \sqrt{3} [/tex]
simplify multiplication:
[tex] \displaystyle 2 GH = 4 \sqrt{30} [/tex]
divide both sides by 2:
[tex] \displaystyle GH = 2 \sqrt{30} [/tex]
QUESTION-3:Recall that, the sum of the interior angles of a triangle is 180°
therefore,
[tex] \displaystyle m \angle G + {60}^{ \circ} + {90}^{ \circ} = {180}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle m \angle G + {150}^{ \circ} = {180}^{ \circ} [/tex]
cancel 150° from both sides
[tex] \displaystyle m \angle G = {30}^{ \circ} [/tex]

Answer:
z = 113
y = 31
Step-by-step explanation:
j || n and line a is their transversal. (given)
Therefore,
z° = 180° - 67° (exterior angles on the same side of transversal)
z°= 113°
z = 113
(5y - 88)° = 67° (exterior alternate angles)
5y - 88 = 67
5y = 67 + 88
5y = 155
y = 155/5
y = 31

Mrs. Giavis has 26 marbles in a bag. She has 13 blue marbles, 10 red marbles, and 3 yellow marbles. What is the probably that Mrs. Giavis will pick a blue marble, not replace it, and then randomly pick a red marble?
Given:
Total number of marbles = 26
Number of blue marbles = 13
Number of red marbles = 10
Number of yellow marbles = 3
To find:
The probability of getting a blue marble then a red marble (without replacement).
Solution:
Total number of marbles = 26
Number of blue marbles = 13
Probability of getting a blue marble is first draw is:
[tex]P(Blue)=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(Blue)=\dfrac{13}{26}[/tex]
[tex]P(Blue)=\dfrac{1}{2}[/tex]
After drawing 1 marble, the remaining number of marbles in the bag is 25.
Probability of getting a red marble is second draw is:
[tex]P(Red)=\dfrac{\text{Number of red marbles}}{\text{Remaining number of marbles}}[/tex]
[tex]P(Red)=\dfrac{10}{25}[/tex]
[tex]P(Red)=\dfrac{2}{5}[/tex]
Now the probability of getting a blue marble then a red marble (without replacement) is:
[tex]P(\text{Blue then red})=P(Blue)\times P(Red)[/tex]
[tex]P(\text{Blue then red})=\dfrac{1}{2}\times \dfrac{2}{5}[/tex]
[tex]P(\text{Blue then red})=\dfrac{1}{5}[/tex]
Therefore, the probability of getting a blue marble then a red marble (without replacement) is [tex]\dfrac{1}{5}[/tex].

Find the value of angle MIJ
Answer:
the value of ∠MIJ is 125
Step-by-step explanation:
You can assume ∠ JIK and ∠MIL are the same and would add to 110 degrees. we know a circle can only contain 360 degrees so if you take 360 - 110 = it leaves 250. and ∠LIK and ∠MIJ are equivalent so if you take your remainder of 250 and divide it by 2 you get 125 degrees.

Homemade applesauce is one of Duncan's favorite foods, so he bought 10 pounds of apples at the farmers' market. His applesauce recipe says that 8 ounces of apples make 1 cup of applesauce. How many cups of applesauce can he make with 10 pounds of apples?
Answer:
20 cups of applesauce
Step-by-step explanation:
8 ounces = 0.5 pounds
Pounds of apples : cups of applesauce
0.5 pounds : 1 cup = 10 pounds : x cups
0.5/1 = 10/x
0.5*x = 1*10
0.5x = 10
x = 10/0.5
x = 20 cups of applesauce
10 pounds of apples will make 20 cups of applesauce
P, Q & R form a right-angled triangle.
R, S & P lie on a straight line.
PS = SQ and
∠
SQR = 46°.
Work out
∠
RPQ
Answer:
m<RPQ = 22°
Step-by-step explanation:
Given:
m<SRQ = 90°
PS = PQ
m<SQR = 46°
Required:
m<RPQ
Solution:
m<SQR + m<SRQ + m<RSQ = 180°
Substitute
46° + 90° + m<RSQ = 180°
m<RSQ = 180° - 136°
m<RSQ = 44°
Find m<PSQ:
m<PSQ = 180° - m<RSQ (Angles on a straight line
m<PSQ = 180° - 44° (Substitution)
m<PSQ = 136°
Find m<RPQ:
∆QSP is an isosceles triangle with two equal base angles. Therefore:
m<RPQ = ½(180° - 136°)
m<RPQ = 22°

Answer:
The two hypotenuses.
Step-by-step explanation:
HL or Hypotenuse-Leg Theorem: two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.
Since we already know the bottom leg of each triangle is congruent, we only need to know the two hypotenuses.
