Question

The sum of the two angles of a quadrilateral is 150degree. The remaining two angles are in the ratio of 3:4. Find the angle​

Answer 1

Answer:

90°, 120°

Step-by-step explanation:

sum of first angle and second angle= 150°

let the angle be x

then third angle= 3x

fourth angle= 4x

the sum of all angles of quadrilateral is always 360°

so, 150°+3x+4x= 360°

= 150°+7x= 360°

= 7x= 360-150

= 7x= 210°

=x= 210/7= 30°

so, third angle= 3x= 3×30°= 90°

fourth angle= 4x= 4×30°= 120°
