Answer:
(D)68°
Explanation:
Given: In ΔPQR, PQ=PR=5 and ∠PQR=68°.
To find: The measure of ∠R.
Solution:
From the given figure, it can be seen that both PQ and PR have the same measure that is 5 in length.
From the property of triangles that is if the two sides of triangle are equal, then the angles made by those sides are equal in measure.
Since, PQ and PR are equal, therefore ∠PQR=∠PRQ=68°.
Hence. the measure of the angle R is 68°.
Therefore, option D is correct.
