Answer:
The actual measure of ∠1 = 40°
Step-by-step explanation:
We are given: ∠1 = 2x+6 and ∠2 = 8x+4
and both angles are supplementary. we need to find the actual measure of ∠1
Supplementary angles: If the angles are supplementary their sum is equal to 180°
In our case ∠1 +∠2 = 180°
2x+6+8x+4=180
Solving the equation to find x, then we can find the actual measure of ∠1

So, value of x = 17
Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

So, the actual measure of ∠1 = 40°
Answer:
The answer is "0.1190".
Step-by-step explanation:
Given:

If it doesn't mean options as an added cost, it would be a total of $34,765.
If it means options as an added cost it would total to $35,140
(2 x 100,000) + (7 x 10,000) + (9 x 100) + (5 x 10) = 270,950
