Answer:
67.5 degrees
Step-by-step explanation:
The first angle is 45 and the second angle is x and the third angle is x (the second and third are equal)
We know the 3 angles of a triangle add to 180 degrees
45+x+x = 180
Combine like terms
45+2x=180
Subtract 45 from each side
45-45 +2x = 180-45
2x= 135
Divide by 2
on each side
2x/2 =135/2
x = 67.5
What are you asking, exactly?
To find the surface area of a cylinder, the formula is:
2
rh + 2
Answer:
well first you need to know the formula of the object then you need to multiply and divide as so
Step-by-step explanation:
you would do 3.14 times the radius times the formula and you would get you answer you radius is half of the formula
Answer:
(3x - x) :v
Step-by-step explanation:
3x - 5 - x =134
2x - 5 = 134
2x = 139
x = 139/2
