Find the value of x. 76 degrees, and 63 degrees

33

Step-by-step explanation:

i'm gonna assume that you were talking about triangle problem :0

Step-by-step explanation:

Triangle: all (three) angles add up to 180 degrees. Always.

Given angles: 76 degrees and 63 degrees.

x must be the degree of an unknown angle that has to be solved.

76 + 63 = 133 degrees

Now subtract 133 degrees from 180 degrees to find the unknown angle.

180 - 133 = 47 degrees = x

ANSWER: x = 47 degrees

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

m∠a is 90°

m∠b is 40°
