Question

Please solve this problem so urgent

Answer 1

since the sides are equal x= 90 degree

Answer 2

Answer:

90°

Step-by-step explanation:

In the figure we can observe two sides are equal

∴ angles opposite to equal sides will also be equal.

Hence we have to angles of given triangle as 45° and 45°

Now,

Sum of all three interior angles of a triangle = 180°

45° + 45° + x = 180°

90° + x = 180°

x = 180° - 90°

x = 90°
