Question

help to solve questions ​

Answer 1

Step-by-step explanation:

Let each of the three equal angles be x°.

Now, sum of angles of a quadrilateral = 360°

⇒ 108° + x° + x° + x° = 360° ⇒ 3x° = 360° – 108°

x° = 252°/3

⇒ x° = 84°

∴ x° = 84°

Hence, each of the three equal angles is 84°.

Answer 2

Answer:

<A=<B=<C

3<A+108= 360°

3<A=360-108

3<A=252

<A= 252÷3

<A= 84°

<A= <B= <C= 84°
