Question

Using the picture above, find the value ofr. Round to the nearest tenth plssssi need helpppppp

Answer 1

Answer:

11.4

Step-by-step explanation:

Since this triangle is a right triangle, we can solve using SOHCAHTOA.

Our angle is 25 degrees and the given hypotenuse length is 27. So, the best trigonometry equation to use would be sine, since it includes the hypotenuse and the opposite side, which is the r length that we are looking for.

Through SOHCAHTOA, sin 25° = $\frac{opp}{hyp}$

sin 25° = $\frac{r}{27}$

r = 27 (sin 25°)

Using a calculator, 27 (sin 25°) ≈ 11.4
