Mhanifa can you please help? I need this done asap and i will mark brainliest!

Answer:

Exterior angles of a polygon sum to 360

94 + 56 + 4.5x + x + 1.5x = 360
150 + 7x = 360
7x = 210
x = 30

Sum of interior angles of a pentagon is:

(5 - 2)*180 = 540

Sum of interior angles of a given pentagon:

72 + 3x + 89 + 99 + 2x = 540
5x + 260 = 540
5x = 280
x = 280/5
x = 56

Tina is saving to buy a notebook computer. She has two options. The first option is to $400 away initially and save $30 every mo

LuckyWell [14K]

Answer:

Let n represent the number of months after Tina would save the same amount using either option.

400 + 30n = 100 + 50n

400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality

400 = 100 + 20n Combine like terms.

400 − 100=100 + 20n − 100 Subtraction Property of Equality

300 =20n

300

20n

15 months=n

After 15 months, Tina will save the same amount using either option.

400 + 30(15)=100 + 50(15)

400 + 450=100 + 750

850 = 850

After 15 months, Tina will save $850 with either option.
