Question

One angle of a quadrilateral is 90 and all rhe other angles are equal. Find each equal angle

Answer 1

$\mathfrak \red{answer}$

angle sum property of quadilateral: <1+<2+<3+<4=360°

90°+<2+<3+<4=360°

Since all the other 3 angles are equal

Therefore

90°+<2+<2+<2=360°

360-90=3<2

270/3=<2

90°=<2,<3,<4

Answer 2

Each angle is 90

as on angle is 90deg and all others are equal.

Using ANGLE SUM PROPERTY.

We get other angles as 90
