Answer:
1. Subtract 2 from both sides.
2. Multiply both sides by 2.
3. Take the square root of both sides.
4. Subtract 5 from both sides.
Applying the trig formula: sin a = cos (90 - a)
cos (2x + 8) = sin (x + 37) = cos (90 - x - 37) = cos (53 - x)

Check by calculator.
x = 15 --> sin (x + 37) = sin 52 = 0.788
cos (2x + 8) = cos (38) = 0.788. Proved
x = - 61 --> sin (x + 37) = sin (- 24) = - sin 24 = - 0.407
cos (2x + 8) = cos (-122 + 8) = cos (- 114) = - 0.407. Proved
Answer:
p≥53
Step-by-step explanation:
the amount of people, assuming the variable p is representing is at least 53 that go to the food truck, so p≥53 means that p is greater than or equal to (≥) 53
13.33 with a little line over the last three. Which makes it known that it is continuous. Or the fraction answer.. 40/3!
The closest fraction to 0.3 is 1/3, which is 0.3 repeating
Hope this helps!!!!!
