Question

an Isosceles triangle en the
third angle is 30 more than each
of the equal angles. Find the angles​

Answer 1

Answer:

We will use angle sum property .

Sum of all interior angle of triangle are 180°

Isosceles Triangle has two same sides .

30° + x + x = 180°

2x = 180° - 30°

2x = 150°

x = 150 ÷ 2

75 °

So angle are 75° , 75°, 30°

Answer 2

Answer:

First angle = 50°

second angle = 50°

Third angle = 80 °

Step-by-step explanation:

let the first angle be x

first angle = second angle = x

third angle = x + 30°

=> x + x + (x+30) = 180°

=> 3x = 180°-30°

=> x = 150/3

× = 50°
