What is the value of x?

Enter your answer as a decimal to the nearest tenth in the box.

Answer 1

tangent (36°) = (opposite side) / (adjacent side)

tan(36°) = x / 15-ft

Multiply each side by 15-ft :

x = (15-ft) times tan(36°) .

from calculator, slide rule, or tables in a book, tan(36°) = 0.727

so

x = (15-ft) times (0.727)

x = 10.9 ft.

Answer 2

So for this, we will be using tangent to solve (Remember that tangent = opposite/adjacent)

In this case, our equation is
`(tan(36))/(1) =(x)/(15)`

For this, all you need to do is cross-multiply, and your answer will be
`x=10.9`
