Question

In the figure angle AOB=60 degree,AB=3cm .what is the measure of angle A

Answer 1

Answer:

where is the figure, man?

Answer 2

Answer:

Concept:

in an isosceles triangle two angles joining the equal lines to the third side are equal.

Given:

Let us assume AOB be triangle in a circle where O is a circle and A, B are points on the circumference

to find:

angle A

Step-by-step explanation:

Since AO and OB are radii of the circle ∴ ΔAOB is a isosceles triangle

∠A =∠B

A+B+C=180°

2A = 180°- 60°

A= 60°
