Trapezoid yesr is an isosceles trapezoid. if m∠yes= 77 °, what is m∠esr?
a) 77°
b) 113°
c) 103°
d) 13°

C) 103°

Step-by-step explanation:

Because this is an isosceles trapezoid, it will have 2 pairs of equal angles. If angle YES is equal to 77°, that means that the angle that is on the same side as it will also equal 77°. Angles YRS and ERS are also equal. Assume that angle equals x. Knowing this, you can use the equation:

77+77+2x = 360

154+2x = 360

2x =360-154=206

x=206/2

x=103°

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
