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

The answer is b. It cannot be c cause the answer would be a negative number. It cannot be a because there would be more than 100 lollipops altogether. And it cannot be d because the answer would be a fraction. There was 29 lollipops altogether. Hope this helps!

In a right-angled triangle, the hypotenuse is 113 and a leg is 112.
melomori [17]

Answer: 15

Step-by-step explanation: Use the formula: a^{2}+b^{2}=c^{2}

Remember c^{2} should always be the hypotenuse or the longest side.

112^{2}+b^{2}=113^{2} ---> evaluate the exponents

12544+b^{2}=12769 ----> subtract 12544 to the other side

b^{2}=225 ---> take the square root of both sides

b=15
