A right angle is 90 degrees
So you 90/4=22.5
Then 90+22.5=112.5

Answer:
A. 30
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin B = 8/16
sin B = 1/2
Take the arcsin of each side
arcsin sin(B) = arcsin (1/2)
B = arcsin (1/2)
B = 30
Answer:
46.6
Step-by-step explanation:
Answer:
- 320 +0.05s ≥ 600
- sales ≥ $5600
Step-by-step explanation:
For sales of 's', Alan's earnings will be ...
320 +0.05s
He wants that to be at least 600, so the inequality is ...
320 +0.05s ≥ 600
__
Its solution is found by subtracting 320 and dividing by 0.05.
0.05s ≥ 280
s ≥ 5600
Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.
Solve for y:
y + 1 = -3/5x + 2.4 (multiply 4 by 3/5 no negatives because negative times a negative is a positive)
y = -3/5x + 1.4
Now graph the y-intercept of 1.4.
Then plot points using slope.
