Question

In the given figure, find the value of x.
​

Answer 1

Answer:

AB=BC

so, x=angleCAB.

90°+x+x=180°

2x=180°-90°

2x=90°

x=45°

Answer 2

Answer:

45°

Step-by-step explanation:

by angle sum property of triangle we know that the sum of angles of triangle is 180°

here angle B is 90° and side AB and BC are equal so the angles opposite to equal sides are equal hence angle A equal to angle C

so, angle A + angle C + angle B =180°

x+x+90°=180°

2x=90°

x=45°
