Determine the measure of each angle
in the triangle.

Step-by-step explanation:

sum of angles of triangle= 180

X+3 +2X-2 + X+19 = 180

4X + 20 = 180

4 X= 160

X= 40

m< A = 2x 40 - 2= 78

m < B= 40+3 = 43

m < C= 40+19 = 59

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
