Question

Which is the best approximation for the measure of angle ABC? 27.7° 31.7° 58.3° 62.3°

Answer 1

Answer:

The correct answer is 58.3 degree.

Step-by-step explanation:

Answer 2

The correct answer is option (c) 58.3°.

Explanation:

• The best approximation for the measure of angle ABC is 58.3°.
• As we seen that the vertex c is making the right angle i,e angle of 90° and also there is an acute angle.
• So, the Hypotenuse will be: 20 cm and the perpendicular is 10.5 cm.
• Now, we have find the best approximation of the angle ABC used the cosx  trigonometric function.
• Therefore, after putting the values in the trignometric function we get 58.3°.
• Hence, the correct answer is option c i.e 58.3°.
