Question

The vertical angle of an isosceles triangle is 90°,find the measurement of each of its base angles. ​

Answer 1

Answer:

the measurement of each of its base angle is 45

Step-by-step explanation:

let each base angle be X.

sum of triangle is 180

90+X+X=180

2x=180-90

2x=90

X=90/2

X=45

so each base angle is 45

Answer 2

Answer:

the measurement of each of its base angle is 45

Step-by-step explanation:

let each base angle be X.

sum of triangle is 180

90+X+X=180

2x=180-90

2x=90

X=90/2

X=45

so each base angle is 45
