The measure of the angle R is
Explanation:
It is given that the lengths of the triangle are PQ = 8 and QR = 3
To find the angle of R using the opposite and adjacent side, we shall use the tangent formula.
where opp = 8 and adj = 3
Thus, substituting these values in the formula, we get,
Multiplying both sides by , we get,
Dividing, we get,
Rounding off to the nearest tenth, we have,
Thus, the measure of the angle R is
