Question

Right triangles 1,2 and 3 are given to its all their angle measures and approximate side lengths

Choose one answer:

4.5 units
5.4 units
9.1 units
10.9 units

Answer 1

5.4 units

Explanation:

From the figure ,it's clear that sin(50) = PQ/7

Then

PQ = 7×sin(50) = 5.362311101833

Therefore the approximate length of PQ I saw 5.4
