Question

two angles of a quadrilateral are 60 degree and 70 degree and other two angles are in the ratio of 8:15 then the remaining two angles angles are :-​

Answer 1

Answer:

Angles in a quad 360°

360-60-70= 230

8x+15x= 230

23x= 230

x=10

8x=80°

15x=150°

Answer 2

The two angles are 80° and 150°.

Step-by-step explanation:

Consider the provided information.

Two angles of a quadrilateral are 60 degree and 70 degree.

The sum of all angles of the quadrilateral are 360 degree.

Other two angles are in the ratio of 8:15

Let the two angles are 8x and 15x.

8x+15x+60°+70°=360°

23x+130°=360°

23x=360°-130°

23x=230°

x=10°

Hence, the value of x is 10°.

Therefore the remaining two angles are:

8×10°=80°

15×10°=150°

Therefore, the two angles are 80° and 150°.
