Answer:
A=101°
Step-by-step explanation:
The two lengths of the rectangle are parallel and therefore the sides of the path form two parallel transversals.
The angle marked 79° and the angle marked A are supplementary ( they add up to 180°)
A+79=180°
A=180-79
=101°
Answer:
m < A = 101 degrees.
Step-by-step explanation:
The transverse line crosses 2 parallel lines (opposite angles of a rectangle are parallel) , so the same side angles add up to 180 degrees.
m < A + 79 = 180
m < A = 101 degrees.
Answer:
14. It is biased, because the store manager sends the survey to a customer who registered. I will send the survey to a customer who is not registered and who is new to the store.
15. This is unbiased, because they chose the students randomly.
Step-by-step explanation:
Volume of Pyramid is given by 1/3 base area x height
From the figure we see the base have equal side x so it is a square .Are of
Base = area of square.
Area of base = area of square = x .x = x2
Volume of Pyramid = 1/3 . base area .height
Volume of Pyramid = 972 cubic inches given.
Height of Pyramid= ½ x inches .
Substituting the values of volume ,height and base area we have:
972=1/3 .x2.1/2 x.
972=1/6 x3
Multiplying both sides by 6 we have:
5832=x3
Taking cuberoot of both sides.
X=18in
Length of the side of base is x= 18in each height is ½ x = ½ .18= 9 in
