When all sides of a quadrilateral are equal (indicated by tick marks on the four sides) in length and connect the opposing vertices with a line, it will form four 90° angles. Therefore, each equation will equal 90.
10x= 90
x+y= 90
3z= 90
The measure of angles 1 and 3 can be solved as they are so:
10x= 90 ➡️ x=9
3z= 90 ➡️ z= 30
The value of x is needed to solve for the measure of angle 2 so plug in the value of x and solve:
x+y= 90
9+y= 90
y= 81
Therefore the answer is a.
Answer:
D. $2071.20
Step-by-step explanation:
The table tells you that Bob's monthly payment on a 4-year loan at 6.5% will be $23.71 per thousand borrowed. The sum of those 48 payments is ...
48 × $23.71 = $1138.08
That means, Bob pays $138.08 in total finance charge for each $1000 he borrows. He is borrowing 15 times $1000, so his total finance charge will be ...
finance charge = 15 × $138.08 = $2071.20 . . . matches choice D

A Variable is a symbol for a number we don't know yet. It is usually a letter like x or y. A number on its own is called a Constant.
The answer is negative, it’s negative because the dots are going down instead of up
