Answer:

15.1feet

Step-by-step explanation:

From the triangle, we are given the following

<S = 25 degree

US = 15 feet = Adjacent

Required

ST = Hypotenuse

Using the trig identity

Cos theta = adj/Hyp

Cos 25 = 15/ST

ST = 15/cos25

ST = 15/0.9912

ST = 15.13feet

Hence the measure of ST is 15.1feet

What is b when sy = 128.4, sx = 327.8, and r = 0.92?
Nana76 [90]

Answer:

0.360

Step-by-Step Explanation:

The equation to find B is as follows:

B = R * (sy/sx)

All of those values are given to you in-question. It’s a matter of plugging in the material and following PEMDAS. For this, the equation becomes; 0.92 x (128.4/327.8), which pans out to be 0.360.

Hope this helped.
