We can find r
Step-by-step explanation:
The law of sine also known as the sine rule, stipulates that the ratio of the length of a side of a triangle and the sine of the angle facing that side is a constant for all the sides of the triangle.
Mathematically, what this means is that;
r/Sin R = q/Sin Q = s/Sin S
Now, for this question, what do we have?
we have angle Q and the side facing it q
We also have angle R.
So the side we can find from here using the sine rule is no other than the side r.
We can find the length of side r from the triangle using the sine rule
And thus we have something like;
9.5/Sine 18 = r/Sine 135
