Question

in an isosceles triangle angles,the equal angles re one-fourth of the vertical angle . find their degree measures​

Answer 1

Answer:

equal base angles = 30° each

vertical angle = 120°

Step-by-step explanation:

let the vertical angle be y

and, the equal base angles be x

therefore,

by the question,

x = y/4

thus,

y + x + x = 180°

y + y/4 + y/4 = 180°

6y/4 = 180°

y = 120°

therefore, x= y/4

x= 120/4

x = 30°
