Please help me with this geometry question!!

x = 60°

Step-by-step explanation:

sum = (n-2) = 180

= (5-2) = 180

it's (5-2) because there is 5 angles.

= 3 = 180

divide both sides and becomes..

= 540

then, you add in all your angles and equal it to 540.

x + (2x) + (3x) + (x + 45) + (x + 15) = 540

collect the like terms.

8x + 60 = 540

subtract 60 from 540.

540 - 60 = 480

divide both sides by 8x.

8x = 480

x = 60°

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5
