Answer:

15.2 cm, 130 m

Step-by-step explanation:

1. The sine of angle Z is XY/17.4; (opposite/hypotenuse);

sin(61) = XY/17.4; multiply both sides by 17.4 to find XY

17.4sin(61) = 15.2 cm

2.

This triangle is made by the anchor of the balloon to the ground, the balloon, and the area on the ground directly below the balloon.

The hypotenuse of the triangle is the 170 m string.

The angle of inclination is 50 degrees.

The height of the triangle will be opposite of the angle of inclination.

Therefore,

sin(50) = height/170 (opposite/hypotenuse)

170sin(50) = 130.2 meters

Paula is now four times the age of Lynn Lynn will be 16 in 10 years how old was Paula four years ago show your work
Dovator [93]
Greetings!

"<span>Paula is now four times the age of Lynn. Lynn will be 16 in 10 years. How old was Paula four years ago?"

If Lynn will turn sixteen in ten years, she must be 6 at the current moment:
16-10=6

Since Paula is 4 times the age of Lynn, Paula must be:
6(4)
=24

24-4
=20 

Paula was 20 years old, 4 years ago.

Hope this helps.

Diana had 41 stickers. She put them in 7 equal groups. She put as many as possible in to each group. She gave the leftover stick
mr Goodwill [35]
She gave Diana, her sister, 6 stickers. This is because 41 divided by 7 is 5 R 6 and there are 6 stickers left if you want each group to have the same amount with no leftovers.
