We have an rectangle triangle
Pythagoras therorem:
hypotenuse²=side₁²+side₂²
hypotenuse=61 feet
side₁=11 feet
side₂=height
(61 feet)²=(11 feet)²+ side₂²
3721 ft²=121 ft²+ side₂²
side₂²=3721 ft²-121 ft²
side₂²=3600 ft²
side₂=√(3600 ft²)
side₂=60 ft.
heigth=60 feet
C. 190
Round each number
55→60.
60→60
65→70
Then add all of your rounded numbers.
60+60+70=190
Answer:
y=1/4x-1/2
Step-by-step explanation:
The slope is .32m, It means that is the fee charged PER MILE DRIVEN. The slope is always the number before any variable like x.
Answer:
![x=\frac{133}{3}^o](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B133%7D%7B3%7D%5Eo)
Step-by-step explanation:
The <u><em>Triangle external angle theorem</em></u> states that :An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see
see the attached figure with letter to better understand the problem
step 1
Find the measure of the interior angle at B
we know that
----> by supplementary angles (form a linear pair)
![m\angle B=180^o-2x](https://tex.z-dn.net/?f=m%5Cangle%20B%3D180%5Eo-2x)
step 2
Find the value of x
Applying the triangle external angle theorem
![86^o+(180-2x)^o=4x^o](https://tex.z-dn.net/?f=86%5Eo%2B%28180-2x%29%5Eo%3D4x%5Eo)
solve for x
![86^o+(180-2x)^o=4x^o](https://tex.z-dn.net/?f=86%5Eo%2B%28180-2x%29%5Eo%3D4x%5Eo)
![4x+2x=266\\6x=266](https://tex.z-dn.net/?f=4x%2B2x%3D266%5C%5C6x%3D266)
![x=\frac{266}{6}^o](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B266%7D%7B6%7D%5Eo)
simplify
![x=\frac{133}{3}^o](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B133%7D%7B3%7D%5Eo)
