Answer:

By using the rule that the interior angles of any triangle equal 180 we see that:

m<ABC+m<CAB+m<ACB=180°

Therefore,

(2x+15)+(x+10)+(3x+5) = 180°

Now we have an equation and can solve for x:

Combine like terms:

(2x+15)+(x+10)+(3x+5) = 180°

6x+30=180°

6x+30-30=180-30

6x=150

x=25

To check our work just plug in 25 for x in each equation and the sum of those answers should add up to 180:

2x+15

2(25)+15

x+10

25+10

3x+5

3(25)+5

75+5

65+35+80=180

x=25 is valid

We know that there are 3 people paying you and you have 92. They are paying you 2 a day. that means we need to multiply 3*2=6 and 6*16=96

What is 92+96=188

That means you will have 188 coins in 16 days
