He deposited $540.16. in cash he deposited 17 one-dollar bills, 4 five-dollar bills, and 6 twenty-dollar bills. what was his total deposit

$540.16

He deposited 17 one-dollar bills:

17 × 1 = 17

4 five-dollar bills

4 × 5 = 20

6 twenty-dollar bills:

6 × 20 = 120

120 + 20 + 17 = 157

He deposited $157 out of $540.16 with the values you gave me.

However, there is $383.16 missing.

I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.

2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)

Next, I add 20 on both sides.

2x + 90 + 3x = 200º

I combine like terms (2x and 3x)

5x + 90 = 200º

I subtract 90 from both sides.

5x = 110º

Divide 110 by 5 to get x.

x = 22

For problem two, I label all the angles I know.

49º + 80º + r = 180º

I add 80 and 49.

129º + r = 180º

I subtract 180 and 129 and get 51º, which is your angle for R.

For angle X, you know that angle R plus angle X equals half of a circle, which is 180º

We know from before that 129º is 180º without R, so X is 129º

I hope this helps! Let me know if I'm wrong!
