Answer:
el numero 1
Step-by-step explanation:
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.
