Answer:a is 52 b is 65
Step-by-step explanation:
a:Write 65% as 65100.
65100 of 80 = 65100 × 80.
Therefore, the answer is 52. If you are using a calculator, simply enter 65÷100×80 which will give you 52 as the answer.
b: it is 65 because it is the same question but in reverse which still gives you the same answer.

Angles of Elevation and Depression are used in measuring heights and distances in trigonometric applications using right triangles. These angles are made when we look up or down to view objects. Devices are available to measure angles of elevation and depression. These measured angles can be used in measuring heights and distance which are either tedious or impractical to measure, by modelling the situation into right triangles
