In A ABC, AB = CA and mC = 27°. Find mZB.
1 answer:
Answer:
since AB and CA is equal, it means that this triangle is an isosceles triangle and that it means that whatever the angle C is, b is also that angle.
so if she is 27 degrees then b is 27° as well
but to find a, you must subtract 180 with the sum of angle b and C
so..
180-(27+27)
180-54
therefore a would be 126°
