The answer for this problem is that x = 60°, or B.
We can solve this problem by using our knowledge of quadrilaterals. In this problem, we need to know that the number of degrees in a quadrilateral is equal to 360, but, the formula to find the number of degrees in a polygon with n sides is (n-2) * 180.
Now that we know that the sum of the angles if 360°, we can add all the angles and solve for x. The angles with the squares are 90°.
2x° + x° + 90° + 90° = 360°
Get x by itself, combine like terms.
3x° + 180° - 180° = 360° - 180°
3x° = 180°
x = 60°, or B.

Step-by-step explanation:
7 friends have a similar cell phone plans. The price of each plan is $x. This means that the basic cost of all the plans is $x. The total basic cost for the 7 plans would be
7 × x = $7x
3 of 7 friends pay an extra $4 per month for unlimited text messaging. The total amount paid by the 3 friends would be
3 × 4 = $12
Therefore, the total cost for the 7 plans would be
7x + 12
Answer: 54
Why? You need to put 3 in for x so you get
2(3)^3
3 to the third power is 3*3*3 which equals 27
2(27)
Now you must do 2 times 27 and you get 54
