Pls help if you can,

Step-by-step explanation:

All the angles in a construction like this one are either 7x or 11x. In this case the acute angle is 7x and the obtuse angle  is 11x

11x + 7x = 180

18 x = 180

x = 10

So 7x = 7 * 10 = 70

11 x  = 11 * 10 = 110

Part C

The relationship is that the acute angle + the obtuse one = 180

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
