Question

In an isosceles triangle one angle is 30°, find the other ​

Answer 1

Answer:

Step-by-step explanation:

in an isosceles triangle opposite angles are equal

so, let other two angle be x

now, 30° + x +x = 180°   [triangle sum property]

                   2x  = 180-30 = 150°

                     x = 150/2 = 75°

so , other two angles are each 75°

hope it helps you very well

Answer 2

We know in an isosceles triangle two side are equal

Let the two equal angles be x

According to the angle sum property of the triangle,

x+x+30⁰ = 180⁰

=> 2x = 180⁰-30⁰

=> x = 150⁰/2

=> x = 75⁰

Therefore the measure of other angles is

1st angle = x = 75⁰

2nd angle = x = 75⁰
