Answer:
132°
Step-by-step explanation:
Quadrilateral ABCD is inscribed in a circle,
So, it is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.

(3x-12)° = (3*48 - 12)° = (144 - 12)° = 132°

First find out what 10 percent of 50 is
Do 50/10
I got 5
Then do 5 times 9 to get your answer
You should get 45. Thanks (:
Step-by-step explanation:
We can turn this into an equation.
Let’s denote the amount of money James makes as X.
Then Lin makes X + 3100.
Together they make 81960.
So combine their earning expressions.
X + X + 3100 = 81960
Solve for X
X = 39430
So James makes $39430 since his earnings are demoted by x.
Lin then makes 3100 + 39430, which is $42530.
The square footage would be 24 feet.
