Question

triangle abc is an isosceles triangle angle A is 30°find angle B and angle C​

Answer 1

Step-by-step explanation:

Since one angle is given, (a = 30°), b = c as it is an isosceles triangle. In an isosceles triangle, two angles are equal. Since b = c, let us take its measure as x. Therefore the measure of angles b and c is 75°.

Answer 2

Answer:

75

Step-by-step explanation:

Since one angle is given, (a = 30°), b = c as it is an isosceles triangle. In an isosceles triangle, two angles are equal. Since b = c, let us take its measure as x. Therefore the measure of angles b and c is 75°.
