What is the value of x?
30
45
55
60

Step-by-step explanation:

From the given figure, it can be seen that ∠TRS=x° and ∠TRV=3x°.

Since, SV is a straight line, thus ∠TRS and ∠TRV forms a linear pair, therefore

Therefore, the value of x is 45°.

Option (b) is correct.

x = 45°

Step-by-step explanation:

Given: Figure

We have to find the value of x

Consider the given figure.

Since, SRV is a straight line and angle on straight line is 180°

Thus,

∠SRV = 180°

also, ∠SRV  can be written as ∠SRT + ∠TRV

⇒ ∠SRT + ∠TRV = 180°

x + 3x = 180

⇒ 4x = 180

Divide both side by 4, we have,

x = 45°

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
