I think that A. 12x+2y-6 is the answer, because 8+4 is 12 and -2+4 is 2 and there is nothing to combine with the 6.

10.) Kelly is flying a kite to which the angle of elevation is
jarptica [38.1K]

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

  • l = 65m
  • θ = 70°

As you can see, there has been made a right angle triangle. So:

sin70 =  \frac{h}{l}  \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.

I need help ASAP) i need both answers (person who gets it right gets a brainlist and 5 stars)
Flauer [41]

Answer:

Part A: 24 meters

Part B: 33 meters²

Step-by-step explanation:

Part A: We know the length of 4 of the sides. The other two sides are 2 m & 1 m. Now add all of those values up. 3 + 7 + 5 + 6 + 2 + 1 = 10 + 11 + 3 = 21 + 3 = 24 meters. The perimeter of the polygon is 24 meters.

Part B: I'll split this into two rectangles: one is 3 by 7, and the other is 6 by 2. (3 * 7) + (6 * 2) = 21 + 12 = 33 meters². The area of the polygon is 33 meters².
