11. You are asked to put a V-shaped roof on a house. The slope of the roof is 53°. What is the measure of the angle needed at th
e vertex of the roof? (Hint: You are given the base angles, and you need to find the vertex angle.)
2 answers:
X=missing angle
53(2)+x=180
106+x=180
180-106= 74
The vertex angle is 74.
The question said that it told you the base angles. A roof would have two equal base angles. The base angles= 53
All the angles of a triangle each 180, (the roof is shaped like a triangle)
So, let's make x the missing angle.
53(2)+x=180
106+x=180
Subtract 106 on both sides.
180-106= 74
The vertex angle is 74.

Answer:
it can be a pain when nobody helps... ur top right is correct
Step-by-step explanation:
heres a screenshot ..
4 = - 3(2) + c
4 = - 6 + c
c = 10
y = - 3x + 10
1/12 would be left of the cake
