In a triangle, the measure of one angle is five more than the first and the third angle is one more than four times the first.

katrin [286]

Answer:

A= 29

B=34

C=117

Step-by-step explanation:

A triangle has three sides and a triangle always adds up to be 180

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

Now since you found A, find the other two by plugging A in!

C = 4(29) + 1

C = 117

Plug in the B equation

B = 29 + 5

B=34

Check your answers

29 + 117 + 34 = 180

Orlov [11]

Answer: 540

Step-by-step explanation:

Given : The owner of a stereo store wants to advertise that he has many different sound systems in stock.

Number of different CD players =6

Number of different receivers= 10

Number of different speakers = 9

We are assuming that a sound system consists of one of each .

Then by Fundamental principle of counting , we have

The number of different sound systems can he advertise = (Number of different CD players)x (Number of different receivers) x(Number of different speakers)

= 6 x10 x 9 =540

Hence, the number of different sound systems can he advertise =540
