vazorg [7]

Answer:

m∠A = 139°

Step-by-step explanation:

Since knowing that:

Supplementary angles = 180 degree

Thus we put that in both equation:

( 7x - 15 ) + ( 2x - 3 ) = 180

Combine like terms & use inverse operations to find the value of x:

( 7x - 15 ) + ( 2x - 3 ) = 180

9x - 18 = 180

9x - 18 + 18 = 180 + 18

9x  = 198

9x/9 = 198/9

x = 22

Hence,  Angle A will have a measure of 7x - 15 which means  7 ×  22 -15 = 154 - 15 = 139°

m∠A = 139°

The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°

m∠ B = 41°

Check Answer by add 139 and 31 which equal 180

valiantina purchased 200 beads dor 48$ if she needs 25 more beads how much will she pay if she is charged the same rate?
Umnica [9.8K]
First find out how much each bead costs. In this case, it is .24 (48/200=.24) Now you simply multiply .24 by 25, equaling 6. She will have to pay 6 more dollars.

A new restaurant is attracting customers with searchlights has a radius of 2 feet. What is the searchlights circumference?
Assoli18 [71]

Answer:

12.56 feet

Step-by-step explanation:

The perimeter of a shape is the sum of all its side.

Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".

The circumference of a circle has the formula:

C=2\pi r

Where

C is the circumference (perimeter of a circle)

r is the radius

Given,

r = 2 feet

We substitute and find the circumference, using 3.14 as \pi,

C=2\pi r\\C=2(3.14) (2)\\C=12.56

Hence, the circumference is 12.56 feet
