Question

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

Answer 1

Answer:

1st Base Angle: 30°

2nd Base Angle: 30°

Vertical Angle: 120°

Answer 2

Answer:

30,30,120

Step-by-step explanation:

let base angle= x

thus vertical angle= 4x

both the base angles of an isosceles triangle are equal

so, x+x+4x = 180 (angle sum property)

6 x= 180

x= 180/6

x = 30

so 4x= 120
