Question

In a parallelogram ABCD, if ∠A= (3x − 12)°, ∠B = 2x − 32 °,find the value of x.
​

Answer 1

Step-by-step explanation:

• Here, In llgm ABCD
• Angle A = (3x-12)° and Angle B = (2x-32)°
• Now,Angle A + Angle B = 180° ( Adjacent angle of parallelogram are supplementary)
• 3x -12 +(2x -32) = 180°
• 3x -12 +2x-32 = 180
• 5x - 44 = 180
• 5x = 180+44
• x = 224/5 = 44.8
