Answer 1

HEYA MATEY ^_^✌️✴✨

GOOD MORNING ..^_^✨

SO THERE YOU GO .....

GIVEN , ONE ANGLE, <A = 90°
<B = <C = <D = x ( let )

THEREFORE,

90° + 3x = 360°
=>3x = 270°
=> x = 90°

THEREFORE,

<A = <B = <C = <D = 90°

Answer 2

$<b>HELLO !$
We know that all the sum of the angles of QUADRILATERAL is 360

Given÷

A=90

B=C=D

so, let angle B be X

So, Angle B,C,D are all angle X

So, total is 3X

But sum of all angles is 360

so,
<b+<C+<D+<A=360

X+X+X+90=180

=>3x+90=180

=>3x=360-90

=>3x=270

=>x=270/3

=>x=90

So,<B=90

<C=90

<D=90
