find the measure of angle x in the figure below:

two triangles are shown such that one triangle is inverted and share a common vertex. the lower triangle has two angles at the base marked as 75 degrees each. the angle at the vertex of the inverted triangle at the top is marked as x degrees.

15°
25°
30°
60°

Step-by-step explanation:

In the given picture , we have two triangles ( one on another ) ,such that one triangle is inverted and share a common vertex. .

Then , the third angles of the lower triangle must be x   [∵ Vertical angles are congruent.]

When we consider the lower triangle, we have

    [ By Angle sum property ]

Hence, the measure of angle marked as x =

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
