Solve for x. <br> (parallelogram)
victus00 [196]

The value of x is 55°

Step-by-step explanation:

Given figure is a parallelogram.

In a parallelogram, the opposite sides are equal and parallel and the opposite angles are equal.

This means that,

in the given parallelogram

m∠A=m∠C=x°

m∠B=m∠D=(2x+15)°

The sum of interior angles of a parallelogram is 360 degrees.

So,

m∠A+m∠B+m∠C+m∠D=360°

Putting the values of angles

x+(2x+15)+x+(2x+15)=360\\x+2x+15+x+2x+15=360\\6x+30=360\\Subtracting\ 30\ from\ both\ sides\\6x+30-30=360-30\\6x=330\\Dividing\ both\ sides\ by\ 6\\\frac{6x}{6}=\frac{330}{6}\\x=55

The value of x is 55°

Keywords: Parallelogram, angles

Phantasy [73]

The correct answer is C because if you use the simple interest formula I=PRT The interest has to be $8000+X=$20,000 (X=12,000) P stands for the beginning amount of money ($8000) the R stands for the rate (you don't know this for sure yet) and the T stands for the amount of time(15 years) $12,000=$8000(R)(15) $8000(15)=120,000 $12,000=120,000(R)  $12,000/120,000=120,000(R)/120,000 R=0.1 then multiply by 100 to get the percent of 10% therefore C is your answer.
