If t=29.6 and r=9.5 find R. Round to the nearest tenth

Answer:
18.7
C
Step-by-step explanation:
This is a trig question. You are going to be using one of the 6 fundamental definitions.
Formula
Trig Function = opposite/hypotenuse
The trig function turns out to be the sine of R
Sin(R) = opposite / hypotenuse
Sin(R) = r / t
Givens
r = 9.5
t = 29.6
Solution
sin(R) = 9.5/29.6
sin(R) = 0.3209
R = sin^-1(3209)
If it is your calculator that you are finding confusing, here is how you put it in.
2nd R
Sin^-1
0.3209
=
R = 18.72 degrees.
The correct answer is C
Answer:
The correct answer option is C. 18.7°.
Step-by-step explanation:
We are given a right angled triangle, SRT, with two known sides, r and s.
We are to find the measure of the angle R.
For that, we will use sin.
[tex] sin R = \frac { r } { t } [/tex]
[tex] tan R = \frac { 9 . 5 } { 2 9 . 6 } [/tex]
[tex] R = sin' 0.320 [/tex]
R = 18.7°
