In ΔOPQ, the measure of ∠Q=90°, the measure of ∠O=26°, and QO = 4.9 feet. Find the length of PQ to the nearest tenth of a foot. The length of PQ is ft.

Given:

In ΔOPQ, m∠Q=90°, m∠O=26°, and QO = 4.9 feet.

To find:

The measure of side PQ.

Solution:

In ΔOPQ,

       [Angle sum property]

According to Law of Sines, we get

Using the Law of Sines, we get

Substituting the given values, we get

Approximate the value to the nearest tenth of a foot.

Therefore, the length of PQ is 2.4 ft.

gdp is the best phrase!

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
