RQPO is a trapezoid. What is the value of x?

2

63°

(6x + 9°

R

18°

Step-by-step explanation:

Find the diagram attached

From the diagram, since the opposite side are parallel, the sum of the adjacent angle is 180 degrees

From the diagram, m<RQP + m<QPO = 180

Given

m<RQP = 6x+9

m<QPO = 63

Substitute

6x+9+63 = 180

6x + 72 = 180

6x = 180 - 72

6x = 108

x = 108/6

x = 18 degrees

Hence the value of x is 18°

Therefore,

Cars:Truck=8:7

Answer is B)8:7

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

Let the father's age be x and son's be y

10 years before-

Father age=x-10

sons age=y-10

Given,

x-10=10(y-10)

x-10=10y-100

Given present age of father=40

therefore,

x=40

40-10=10y-100

10y-100=30

10y=130

y=130/10

y=13

Therefore present age of son=13years
