Question

The opposite angles of a cyclic quadrilateral are
(3x + 10) and (2x +20)°. Find the angles.

Answer 1

Answer:

3x+10 + 2x +20 = 180

then, 5x + 30= 180

5x=150

then, it's x= 30.

so, the angles are (3×30+10)and (2×30+20)

then, 100 and 80.

i hope it helps. please mark me brainliest. ☺☺☺

Answer 2

Answer:

Step-by-step explanation:

(3x + 10) + (2x + 20) = 180 (since opp angles of a cyclic quad is 180)

5x + 30 = 180

5x = 150

x = 30

Therefore

Angles = 1) 3x+10

= 3(30) + 10

= 90 + 10

= 100

2) 2x + 20

= 2(30) + 20

= 60 + 20

= 80

Hope it helps,
