Answer:
A
Step-by-step explanation:
sin57° = 
= 
= 
∠ P = 180° - (90 + 57)° ← sum of angles in triangle
∠ P = 180° - 147° = 33° , then
cos33° = 
= =
Thus the 2 ratios used to solve for x are A
Possible Answers:
1. b = 1.5
2. b = 20
3. b = 4
STEP-BY-STEP:
1. -12 ÷ -8
2. b + 20 = 8
3. b + -12 = -8
EXTRA:
Please mark me as brainliest.
This took about 10 minutes to figure out, and write the equations, because I had to re-figure out how I got the original answers.
Answer:
The 20 mph headwind slows the plane down. This is because the headwind comes at the head of the plane and goes in the opposite direction of the plane.
So the plane's actual speed (with the wind included) is 550-20 = 530 mph.
Good luck!
