Question

in an isosceles triangle, the base angle is twice as large as vertex angle find the angle of triangle​

Answer 1

Answer:

72 and 72

Step-by-step explanation:

In an isosceles triangle , base angles are equal

LET vertex angles be x

Then, Base angles will be 2x and 2x

SUM OF ANGLES OF TRIANGLE IS 180°.

Therefore,

2x + 2x + x = 180°

5x = 180°

=> x = 36°

ANSWER =

VERTEX ANGLE = 36°

BASE ANGLES ARE EQUAL TO = 36° × 2

= 72° & 72°
