<h3>what are trigonometric ratios?</h3>
Trigonometric ratios are ratios of the sides of a right-angled triangle.
They are used to relate the sides of a triangle with their angles.
Examples are cosine, tangent, sine etc.
Analysis:
length r is facing angle R, length s is facing angle S, length q is facing angle Q.
in order to find angle R we need to find the length of q first.
using cosine rule,
= + -2srcosQ
= + -2 x 30.6 x 24.4cos15
= 936.6 + 595.36 -1493.3(0.9659)
q = 9.5
using sine rule,
=
9.5 sinR = 24.4sin15
sin R = 24.4(0.2588)
sin R = 6.31
R = arc(sin) 6.31 = 41.5°
In conclusion, the measure of angle R is 41.5°
