It’s 13x-12y+6x2 !! (2)

It’s 2. 13x- 12y + 6x2 because 8x + 5x is 13x. There are no other y values so it stays -12y. 2x2 + 4x2 is 4 + 8 which is 12 so therefore (6x2)

A staircase has an angle of elevation of 28° anı
AveGali [126]

Hi there!

We can use right-triangle trigonometry to solve.

We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.

cosθ = Adjacent/Hypotenuse

We can plug in what is given:

cos(28) = A/17

Solve for 'A':

17cos(28) = <u>15.01 ft</u>
