Question

The figure to the right is a parallelogram. If AD =2× - 10 and BC =× + 30, then BC =______. a. 50 b.60 c.70 d.80. With solution.​

Answer 1

$\mathfark \pink {Answer\:is\:c. 70}$

The measure of Segment BC is 70

$\huge \pink {solution}$

The equation will be

2x - 10 = x + 30

2x - x = 30 + 10

x = 40

Just substitute the value of x

AD = 2x - 10

= 2(40) - 10

AD = 70 TRUE

BC = x + 30

BC = 40 + 30

BC = 70 TRUE
