Question

find x please give right answer step by step explainstion​

Answer 1

Answer:

X= 45°

Step-by-step explanation:

An angle is already given i.e. 90°

Since the sides are equal their opposite angles will also be equal.

Hence,

Angle R = X

By angle sum property of triangle

X + 45° + 90° = 180°

X = 180° - 135°

X = 45°

Hope it helps ☺️

Answer 2

Let R, B and C be the three vertex of ∆RBC

In ∆RBC,

angle RBC = 90°

RB = BC

Therefore, angle RCB = angle CRB = x

angle CRB + angle RCB + angle RBC = 180°

x + x + 90 = 180

2x + 90 = 180

2x = 90

x = 45
