In the figure below, k || m. Find the values of y and x.
Answer:
x = 23
y = 105
Step-by-step explanation:
It's given that lines 'k' and 'm' are the parallel lines and 'l' is a transversal line.
Therefore, y° + 75° = 180° [Sum of consecutive exterior angles = 180°]
y = 180 - 75
y = 105°
And y° + (4x - 17)° = 180° [Linear pair of angles are supplementary]
105 + (4x - 17) = 180
4x + 88 = 180
4x = 180 - 88
4x = 92
x = 23

The measure of H=90°, the measure of G=80° and FG=75 feet. Find the length of HF to the nearest tenth of a foot
Answer:
The length of HF is 73.9 feet.
Step-by-step explanation:
Let the length of HF be represented by x. So that applying the appropriate trigonometric function to the triangle FGH, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Where θ is the angle given in the triangle = [tex]80^{o}[/tex].
Then,
Sin 80 = [tex]\frac{x}{75}[/tex]
⇒ x = Sin 80 x 75
= 0.9848 x 75
= 73.86
x = 73.9
Thus, the length of HF is 73.9 feet.

There are 3 consecutive integers that add up to 15. What is the least of these integers?
Answer:
The answers are 4,5,6,
the answer you are looking for is 4
Step-by-step explanation:
the first thing you have to do is define a variable for stuff that you don't know. In this problem, you don't know any of the integers, so you should assign a variable to them.
will put the first integer as n. The second integer, since it is right after the first, will be n+1. The third integer, since it is right after the second, will be (n+1)+1=n+2. consider the integers 1, 2, and 3. 2 is one more than 1, or in other words, 2=1+1. same for 3, except 3 is two more than 1, so 3=1+2. Since the integers are consecutive, each is one more than the last.We're told that the sum of our three integers is 15. Therefore, n+(n+1)+(n+2)=15 Solving this equation is pretty straightforward:
3n+3=15
3n=12
n=4 That means our first integer is 4. Our second integer is 4+1, or 5, and our third integer is 5+1, or 6. Our answer is confirmed because 4+5+6=15

TrianglesΔBE -ΔAE= ΔAB
ΔAB=180°-148°
ΔAB=32°
ΔBE -ΔAB-ΔBC=ΔCD (Congruent angles)
ΔCD = 180-32-87
ΔCD =62
EC=61+32

aurora scored 572 marks out of 650 belle scored 450 out of 500 for the annual examination.
a. who performed better and by how much.
b .what percentage she scored
Step-by-step explanation:
a. Belle as she only missed 50 questions where as Aurora missed 78. (500-450) and (650-572)
b. Belle scored 90% (450/500=0.9)
Answer:
a. Belle scored better, by scoring 2% more than Aurora.
b. She scored 90%
Step-by-step explanation:
Make your denominator out of a 100
So you will divide by 6,5
572÷6,5/650÷65
= 88/100
=88%
And divide the other by 5
450÷5/500÷5
=90/100
=90%

x=??
y=??
Answer:
x = 55
y = 45
Step-by-step explanation:
In similar triangles, the ratio between similar sides are the same. So,
AB/ED = BC/EF = AC/DF
Substitute values that they give
6/15 = 18/y = 22/x
Solve 6/15 = 18/y by cross-multiplying
6y = 15*18 = 324
Divide both sides by 6
y= 45
Solve 6/15 = 22/x by cross-multiplying.
6x = 22*15 = 330
Divide both sides by 6.
x = 55
Because there is some dispute between the answers, let's check the ratios.
6/15 = 18/45 = 22/55
0.4 = 0.4 = 0.4
True, x = 55 and y=45
since triangle abc~ def
their sides will be proportional
AB/de=ac/df
6/15=22/x
doing crisscrossed multiplication
6x=22×15
x=22×15/6=55
again
AB/de=BC/EF
6/15=18/y
doing crisscrossed multiplication
6y=15×18
y=15×18/6=15×3=45

The perimeter of a rectangle is 72 m. The width of the rectangle is 16 m. What is the area of the rectangle?
Answer:
320m
Step-by-step explanation
a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
