Question

Triangle pqr is a right triangle. what is the best approximation of the length of segment pq? (Note:tan76°)

15.89 cm
16.04 cm
16.76 cm
17.04 cm ​

Answer 1

PQ = 16.04cm

Explanation:

θ = 76°

QR = 4cm

PQ = ?

Since it's a right angle triangle,

QR = adjacent

PQ = opposite

Tanθ = opposite/adjacent

Tan76 = pq / 4

PQ = 4tan76

PQ = 4 * 4.010

PQ = 16.04cm
