1) C. 100

a pentagon has 540 degrees 

130 + 130 + 90 + 90 + x = 540
440 + x = 540 
x = 100

2) C. 169

a hexagon has 720 degrees

151 + 135 + 115 + 75 + 75 + x = 720
551 + x = 720
x =169

Solve the equation <br> 3 1/4x=7 3/7
Artist 52 [7]

Answer:

\frac{217}{292}

Step-by-step explanation:

the given equation is

\frac{31}{4x} = \frac{73}{7}

cross multiplication gives

⇒ 31 * 7 = 4x * 73

⇒ 217 = 292 x

Dividing both sides by 292 will lead us to

⇒ \frac{217}{292} = \frac{292*x}{ 292}

cancelling out 292 on RHS

⇒ \frac{217}{292} = x

or

x=\frac{217}{292}
