Question

In the given figure AOB is the diameter of the circle and AC=BC. Find angle CAB?​

Answer 1

Answer:

Answer is 90

Step-by-step explanation:

because when diameter form angle on any point of circle then it form 90

Answer 2

Given: AOB is the diameter of the circle

∠ACB = 90°

AC = BC

Now, according to the property, we know that angles opposite to equal sides are equal

Therefore, ∠CAB = ∠CBA

We have to find ∠CAB

We also know that, sum of angles of a triangle is 180°

So, ∠ACB + ∠CAB + ∠CBA = 180°

90 + 2∠CAB = 180

2∠CAB = 90

∠CAB= 45°

Hence, measure of ∠CAB is 45°
