In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches. Find the measure of ∠P to the nearest degree.

Given:

In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.

To find:

The measure of ∠P to the nearest degree.

Solution:

According to the law of cosine:

Using law of cosine in triangle NOP, we get

Putting the given values, we get

Taking cos inverse on both sides, we get

Therefore, the measure of ∠P is 33°.

33° is the answer.

kinda in a hurry, but this is the answer to Deltamath

1. minimum

2. 6400

3. eight

hope this !
