Answer:
He gets 32, $10 bills.
Step-by-step explanation:
He puts in $630.
3 times $50 equals $150.
8 times $20 equals $160.
$150 plus $160 equals $310.
$630 minus $310 equals $320.
$320 divided by 10 equals 32.
So he gets 32, $10 bills.
Answer:

Step-by-step explanation:
According to congruent chords and arcs theorem, if
then
.
This means that
Thus:
(full circle = 360°)



Plug in the values into the equation


Add like terms

Subtract 36 on both sides


Divide both sides by 12

The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
