In AABC, the measure of A is 108° and the
measure of B is 38° . What is the measure of
C?

∠C=34

Step-by-step explanation:

The interior angles of a triangle add to 180 degrees, so

∠A +∠B+ ∠C=180

We know that ∠A is 108, and ∠B is 38, so we can substitute them in

108+38+∠C=180

Combine like terms by adding 108 and 38

146+∠C=180

Subtract 146 from both sides

∠C=34

$X = $12y

Step-by-step explanation:

In this question, we are asked to give an expression to represent the amount of money charged to a man who stayed in a motel for a particular number of days.

Firstly, we need to know the amount of money charged per day. This is visible from

the question and it is equal to $y.

Secondly, the number of days/night stayed is 12 days. This means that the amount of money he was charged is 12 * y = $12y

Since the amount of money charged is equal to $x, the amount to pay can be expressed in terms of y and x to be

$X = $12y
