Answer 1

Answer:

Let ABCD is a rectangle:-

AB= CD and BC= AD. (opp. sides of rectangle)

So,

$\blue {\angle \: c = \angle \: d \: \: = \angle \: x( \angle \: \: opp. \: to \: equal \: sides)}$

Now,

$\orange{ \angle \: c + \angle \: d = 180 \degree \: \: (co. \: interior \angle)}$

$\pink{x + x = 180 \degree }\\ \green {2x = 180 \degree}$

$\boxed {\red{x = 90 \degree}}$

Hence, proved.
