Answer:
(1.5,-2.6)
Step-by-step explanation:
Given the polar coordinates (-3,60°).
Let our Cartesian coordinates be (x,y)
#We know that when converting the rectangular coordinates (x,y) to polar (r,θ), then:

#Using the illustration above, we can express our polar coordinates as:

#Solve simultaneously to solve for x and y:

Hence, the Cartesian coordinates are (1.5,-2.6)
Answer:
Maybe the same as the angle of F (46)
Step-by-step explanation:
If you see the two shapes are the same. but different size. so therfore the angles are same.
5.25 gallons is your answer
Answer:
Step-by-step explanation:
Balloon - B, stake - S, point at ground - G
<u>Given:</u>
- BS = 90 ft
- m∠BSG = 62°
- BG = x
<u>Use sine and solve for x:</u>
- BG/BS = sin ∠BSG
- sin 62° = x / 90
- x = 90 sin 62 deg
- x = 79 ft (rounded)
