Can somebody help me? With those three problems please

15.

16. m<V = 103°

17.

Step-by-step explanation:

15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°

Therefore:

Solve for x

Add like terms

Subtract 112 from each side

Divide both sides by 31

16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:

Solve for x

Add like terms

Subtract 321 from each side

Divide both sides by 21

m<V = 5x + 8

Plug in the value of x

m<V = 5(19) + 8 = 95 + 8

m<V = 103

17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.

Therefore:

Solve for x

Add 18 to both sides

Divide both sides by 9

d? maybe

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
