Answer:
x = 5
Step-by-step explanation:
Given
13 = - 7 + 9x - 5x , that is
13 = - 7 + 4x ( add 7 to both sides )
20 = 4x ( divide both sides by 4 )
5 = x
Answer: 28/r+4
Step-by-step explanation: Divide each term by r + 4 and simplify
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.
I hope this helps!
