There are 4 triangles, all in all.
The total interior angle is 180.
180 = 69 + 43 + (1)
(1) = 180 - 69 - 43
(1) = 68
180 = 112 + 41 + (2)
(2) = 180 - 112 - 41
(2) = 27
180 = 66 + 44 + (3)
(3) = 180 - 66 - 44
(3) = 70
180 = 109 + 29 - (4)
(4) = 180 - 109 - 29
(4) = 72
Answer:
Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}Range: (−∞,∞),{y|y∈R}

Answer:
1. y² - 3x - 18
2. 4x² - 33x + 35
3. 12x² - 11x + 2
Step-by-step explanation:
All we do with these questions are expanding the factored binomials. Use FOIL:
1. y² + 3y - 6y - 18
y² - 3y - 18
2. 4x² - 28x - 5x + 35
4x² - 33x + 35
3. 12x² - 3x - 8x + 2
12x² - 11x + 2
Answer: Each donor donated $70.5 per lap.
Step-by-step explanation:
1. If she got 8 donors and each one of them sponsored 5 laps, then the total number of laps was:
laps
2. Hailey raised a total of $2,820, therefore, you can calculate the amount of money donated by each donor (which you can call 
) by dividing $2,820 by 40 laps, as you can see below:
