120 because 180 divided by 120 is 1.5 which is 150%
I think we have to use Pythagorean Therom here
a² + b² = c²
First we need to know the height of the Triangle (which is YT)
Let "b" be the height YT:
22² + b² = 77²
484 + b² = 5929
b² = 5929 - 484 = 5445
√b² = √(5445)
b = √5445 = 73.79ft
Now that we have the height lets find the missing base(YK):
We are going to use the same formula, but this time to find the base and with a different triangle.
a² + 73.79² = 87.5²
a² + 5444.96 = 7656.25
a² = 7656.25 - 5444.96
a² = 2211.29
√a² = √(2211.29)
a = √2211.29 = 47.02
Now we can add the bases together to find x.
Bases "VY" and "YK"
x = 22+47
x = 69
Answer:
A
Step-by-step explanation: I just guessed
Answer:
c
Step-by-step explanation:
let the actual height of the car be represented by x
now to the question
1/15 = 8/x
x=15×8
x=120cm
height of car= 120 cm or 1.2 M
Answer: x = 1, y = -7
Step-by-step explanation:
![-4x=y+3\\y=-7](https://tex.z-dn.net/?f=-4x%3Dy%2B3%5C%5Cy%3D-7)
Then substitute y=-7 in -4x=y+3
![-4x=-7+3\\-4x=-4\\x=1](https://tex.z-dn.net/?f=-4x%3D-7%2B3%5C%5C-4x%3D-4%5C%5Cx%3D1)
