Question

Find the measure of angle BAC

Answer 1

Answer:

<BAC = 50

Step-by-step explanation:

In triangle ABC is an isoceles triangle

AC=BC

<A = 2x+20

<B = 50

Since AC=BC

<ABC=<BAC (angles opposite to equal sides are equal)

50 = 2x + 20

= 2x = 50 - 20

= 2x = 30

= x = 30/2

= x = 15

Therefore, <BAC = 2x + 20

= 2(15) + 20

= 50
