Part C) What is the measure of angle A, B, & C? Show your work and make sure to identify which is which.

please help this is 2 days overdue :(

  (A)  3(x +5) +(5x +15) +7x = 180

  (B)  x = 10

  (C)  A = 45°, B = 65°, C = 70°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  m∠A +m∠B +m∠C = 180°

  3(x +5) +(5x +15) +7x = 180 . . . . . substitute given expressions

__

  15x +30 = 180 . . . . . . . . . . . . . simplify

  15x = 150 . . . . . . . . . . . . . . subtract 30

  x = 10 . . . . . . . . . . . . . . divide by 15

__

The angle measures are found from the given expressions:

  m∠A = 3(x +5) = 3(10 +5) = 45

  m∠B = 5x +15 = 5(10) +15 = 65

  m∠C = 7x = 7(10) = 70

m∠A = 45°, m∠B = 65°, m∠C = 70°

answer

106 emergencies

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
