Answer:
51.2feet
Step-by-step explanation:
Given;
Horizontal distance = 40feet (Adjacent)
Angle of elevation = 52 degrees
Required
Height of the pole H (Opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 52 = H/40
H = 40tan 52
H = 40(1.2799)
H = 51.2 feet
Hence height, h, of the flagpole to the nearest tenth is 51.2feet
Answer:
-2, -5, 2, then 5
Step-by-step explanation:
Answer: The measure of non-reflex ∠DOB is 108° and the measure of reflex ∠DOB is 252°.
Explanation:
It is given that the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y.
From the given figure we can say that angle AOC and COB are supplementary angles and their sum is 180 because they are lies on a straight line.
Therefore the value of y is 72.
Therefore the reflex and is 252 degree.
The measure of non-reflex ∠DOB is,
Therefore, the measure of non-reflex ∠DOB is 108° and the measure of reflex ∠DOB is 252°.
