Question

The sum of the interior angle measures of a quadrilateral is 360 degrees. Angle Q= 2b degrees is 2x the measure of angle p= b degrees angle r is (3b -19) degrees and angle s is (3b + 10) degrees. Find te value of b.

Answer 1

b = 61

Step-by-step explanation: In quadrilateral PQRS,

=> angle Q + angle P + angle R + angle S = 360°

=> 2b + b + (3b-19) + (3b+10) = 360°

=> 9b - 9 = 360°

=> b = 369/9

=> b = 61
