Question

the ratio between a base angle and the vertical angle of an isosceles triangle is 1:4 . find each angle of the triangle.​

Answer 1

Answer:

all the angles are 30 degree,30 degree, 120degree

Answer 2

Answer:

30°, 30°, 120°

Step-by-step explanation:

let the base angle and vertical angle be x and 4x...

therefore,

x+x+4x=180 (sum of all the angles of a triangle is 180)

=>6x=180

x=30 degree

4x=30*4=120 degree

ans) 30°, 30°, 120°
