Question

In a right angled triangle where angle A = 90 and AB = AC. What are the value of angle B
​

Answer 1

Answer:

45°

Step-by-step explanation:

angle A + angle B + angle C =180°

90 + x + x =180

2x =180-90

2x =90

x = 90/2

x = 45°

Hence angle B is equal to 45°

Answer 2

Step-by-step explanation:

angle B is of 45 ° because one angle is 90 degree and two sides are equal so you can take the angles as X and by linear equations you can solve it very easily

let one angle be x

so,

X + X + 90 =180°

2x = 180 - 90

2x = 90

x = 45 °
