In triangle pqr, the measure of zr=90°, the measure of zp=51°, and qr = 38 feet. find the length of pq to the nearest tenth of a foot.

Therefore Length of PQ is 48.9 foot.

Step-by-step explanation:

Given:

In Triangle PQR,

∠R = 90°

∠P = 51°

QR = 38 feet = side opposite to angle P

To Find:

PQ = ? = Hypotenuse

Solution:

In Right angle Triangle PQR Cosine Identity we get,

Substituting the values we get,

Therefore Length of PQ is 48.9 foot.

the two may have that, even a breakdown is probably offered
