Question

plzzz solve this and don't give me irrevelant replies otherwise I will report him/ her and with explaination​

Answer 1

Answer:

Three angles of a quadrilateral are in ratio 4 : 5 : 3

Let the mentioned angles be 4x, 5x,  3x

also

5x – 3x = 42°

2x = 42°

x = 21°

⇒Three angles are 3 × 21, 4 × 21, 5 × 21

= 63, 84, 105

Now we know that sum of all the angles of quadrilateral is 360°

⇒ fourth angle = 360° – sum of other three angles

= 360° – (63° + 84° + 105°)

= 360° – 252° = 108 °
