Answer:
13 cm
Step-by-step explanation:
A^2+12^2=15^2
A^2+144=225
A^2=81
A=9
9x2=18
31-18=13 cm

What is the length of line segment HJ?
Answer:
b = 5√3 (units)
Step-by-step explanation:
To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.
In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.
a^2+b^2 = c^2 (pythagorean therorm)
5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)
25+b^2 = 100 (square the numbers)
b^2 = 75 (subtract 25 from both sides)
b = √75
b = √25 * √3 (factor out√75)
b = 5 * √3 (find square root of√25)
b = 5√3

Alexis wrote 28 - 8 = 20. Then she
wrote 28 -8 + 9 = 20 – 9. Are her
equations balanced? Explain.
Answer:
no this is because 28-8+9=29 and 20-9=11
Step-by-step explanation:
Answer:
Her equation is not balanced.
Because 28 - 8 + 9 = 20 - 9
29 = 11 ( its not balanced)
She put the same symbol or sign on both side.Here she put different sign on both side .so this equation is not balanced.

Which equation can be used to solve for x in the following diagram?
7xº
11x°
Answer:
7x° + 11x° = 90°
(Required equation)
Step-by-step explanation:
7x° + 11x° = 90°
(complementary angles)
18x° = 90°
18x = 90
x = 90/18
x = 5

Write down the value of angle y, giving a reason for your answer
Y=
Other angle given is 67 degrees
Answer:
y would be 67 as well.
Step-by-step explanation:
they are alternate interior angles. hope it helps
In part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
Part(a)
We have a triangle shown in the picture.
The two lengths of a triangle are equal.
The angle opposite to the sides will be equal.
As we know,
The triangle's interior angles add up to 180°.
180 = 55 + 55 + x
x = 180 - 110
x = 70 degrees
In part (b)
There are two parallel lines shown in the picture.
The angle y will be the same as 67 degrees because two parallel lines are cut by a transversal line.
Thus, in the part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

Answer:
[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
Find the average by adding the 2 fractions and dividing the sum by 2
[tex]\frac{1}{2}[/tex] + 1 [tex]\frac{1}{4}[/tex]
= [tex]\frac{1}{2}[/tex] + [tex]\frac{5}{4}[/tex]
= [tex]\frac{2}{4}[/tex] + [tex]\frac{5}{4}[/tex]
= [tex]\frac{7}{4}[/tex]
Then
[tex]\frac{7}{4}[/tex] ÷ 2
= [tex]\frac{7}{4}[/tex] × [tex]\frac{1}{2}[/tex]
= [tex]\frac{7}{8}[/tex]

y= -3x + 1 and y= x - 3
Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2
