Answer:
40
Step-by-step explanation:
52= 1/2(64 + x)
52 = 32 + 0.5x
52-32= 32-32 + .5x
20=.5x
Divide both sides by .5x
X = 40.

Answer:
x=29
Step-by-step explanation:
the line in the middle of the triangle is at a right angle, so each side of it must equal 90 degrees, so then 90=3x+3, 90-3=3x then you simply, 87=3x which equals x=29.
The problem is actually already factored for you. They are asking you to just set the equation to zero. Find the zeros.
