Answer:

Given the 2 values, height and the base, of these 2 triangles, we can assume that they are similar (meaning they share the same angles) as we have no other information to determine the height of the tree.

Therefore, if these triangles are similar, their corresponding sides are proportional. In other words, PZ/RT = QZ/ST or RT/PZ=ST/QZ

Hence, if we find the ratio of this, we can use it to find the side h

QZ/ST=PZ/RT

48/12=PZ/4

PZ/4=48/12

(PZ/4)3=48/12

PZ(3)/12=48/12

48/3=16

16=PZ.

The radius of the sphere is 9 inches. Which equation can be used to find the surface area of the sphere?

Answers

Answer:

Option (2)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area = 4πr²

Here 'r' = Radius of the sphere

We have to calculate the surface area of a sphere with radius r = 9 inches.

By substituting the value of r in the formula,

S = 4π(9)²

Therefore, Option (2) will be the correct option.

Answer:

B.    S = 4 pi r squared = 4 pi (9) squared

Which of the following represents the measures of all angles coterminal with a -220° angle?
O 360 + 140n, for any whole number n
O 360 + 140n, for any integer n
O 140 + 360n, for any whole number n
O 140 + 360n, for any integer n

Answers

Answer n 9 Explanation 140 degrees is the measure of each angle and the sum of ... So degrees and radians are related by the following equations 360 2 ... Measure angles in whole number degrees using a protractor.

The measurement of all angles co-terminal with a -220° angle is represented by 140+ 360 n, for any integer number n.

What are Co-terminal angles?

These are the angles which shares the same initial line or terminal side. They are obtained by adding or subtracting 360° from the given angles.

Given, angle is -220° then its one positive co-terminal angle= -220°+360 = 140°

So, 140° is a positive co-terminal angle of -220°.

Therefore, co-terminal angle must be the type of 140°+360° n,
