Answer:
A = 32 degrees
Step-by-step explanation:
The triangle ABC given in the diagram is an isosceles triangle.
An isosceles triangle us a triangle that has two equal sides and two equal angles. The two angles are the base angles. In our diagram, the two base angles are angle A and angle C. The sides opposite the base angles are the two equal sides.
In the diagram, the two equal sides are AB and BC. Both lines are marked with a stroke each and that shoes equality.
Sum of the angles in a triangle is 180 degrees.
(A + B + C) degrees = 180 degrees
Since angle A = angle C ,
C= 2A
2A + 118 = 180
2A = 180 - 118 = 62
A = 62/2 = 31 degrees
