Question

The following is a parallelogram. What does A=, B=, X=, QR= and Angle QRS=

Answer 1

a = 4

b=2

x=18

QR =16+1=17

Angle QRS =59

Explanation:

4a+1 = 2a + 9

2a = 8

a = 4

6b = 11b-10

-5b=-10

-b= -2

b=2

6x+13 = 7x - 5 (opposite angles are equal)

-x=-18

x=18

QR =16+1=17

Angle QRS = 180 - 18•6+13 =59 (PQR + QRS = 180)
