What is the measure of angle r shown below, given r = 10, q = 20, and q = 100°? round the answer to the nearest tenth.0.5° 2.0° 29.5° 50.5°

Answer : 29.5°

Given r = 10, q = 20, and Q = 100°

From the attached figure we can see that two sides and one angle is given

We use sine rule to find angle R

In triangle QRS

r = 10, q = 20, and Q = 100°

Replace all the values

=sin R

0.4932403876 = sin (R)

R=

R= 29.5 degrees

i think it is c, not positive though
