If slope angle is 25° over a 70" length, what is the change in elevation?

Find opposite side
theta = 25
adjacent = 70

tangent = opposite/adjacent

tan(25) = O/70
*70 *70

70tan(25) = Opposite

32.64" is your answer

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
