a contractor wants to design a triangular window as shown below. which expression below is equivalent to the angle that must be formed at the apex of the window?

i don't think there is enough

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.

you!
