AB =AC, measure of <A =x°Measure of <B =

Since AB = AC, we have isosceles triangle ABC. Therefore, the measure of angle B is also x°.

To find the measure of angle B in terms of angle A, let's use the information provided:

Given: AB = AC

Since AB is equal to AC, we can conclude that angle B is equal to angle C. Let's denote angle C as y°.

So, measure of angle B = measure of angle C = y°.

Now, we are given that measure of angle A = x°.

To find the relationship between angle A and angle B, we can use the fact that the sum of angles in a triangle is 180°.

In triangle ABC, we have:

Angle A + Angle B + Angle C = 180°

Substituting the values we know:

x° + y° + y° = 180°

Combining like terms:

x° + 2y° = 180°

Now, we can solve this equation to find the relationship between x and y.

Subtracting 2y° from both sides:

x° = 180° - 2y°

Finally, we can conclude that the measure of angle B in terms of angle A is:

Measure of <B = 180° - 2y°
