to the top of a building from two different locations,
The measurements are shown on the diagram.
What is angle A? degrees

Answer 1

Answer:

The answer is 138*

Step-by-step explanation:

The next one is 7

And the length of side X is 47m

The building is 31m tall

plz rate and don't let this get removed people need the help rn

Answer 2

Applying the linear pair theorem, the measure of angle A is determined as 138 degrees.

What is the Linear Pair Theorem?

• The linear pair theorem states that if two angles lie on a straight line, they form a linear pair.
• The two angles in a linear pair add up to give the sum of 180°, this means the angles are supplementary.

Thus, the diagram attached below shows the building and the measures given.

m∠A = 180 - 42

m∠A = 138°

In summary, applying the linear pair theorem, the measure of angle A is determined as 138 degrees.
