Question

In a parallelogram ABCD Angle B equals to 4 x minus 5 and angle the equals to 3 X + 10 calculate Angle B and angle C

Answer 1

Answer:

Step-by-step explanation:In parallelogram adjacent angles are supplementary.

angleA+angleB=180°

4x-5+3x+10=180°

7x+5=180°

7x=175

x = 175/7

x = 25

angle A= 95°

angleB= 85°

opposite angles of parallelogram are equal.

angleC=angleA=95°

Answer 2

Answer:

B=4x-5

C=3x+10

B+C=180°(Adjacent angles)

7x=180-5

x=175/7

x=25°

Therefore, B=95°

C=85°.
