Answer:
c
Step-by-step explanation:
The height of the balloon above the ground is about 7.07 feet.
<h3>
What is trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the balloon from the ground, hence:
sin(45) = h/10
h = 7.07 feet
The height of the balloon above the ground is about 7.07 feet.

Answer:
E: The study was not comparative—only one treatment was used.
Step-by-step explanation:
Well-designed experiments should involve comparisons of at least two treatment groups, one of which could be a control group.

Step-by-step explanation:
<u>Circle Theorem vocabulary</u>
- <u>Chord</u>: a straight line joining two points on the circle.
- <u>Inscribed angle</u>: the angle formed (vertex) when two chords meet at one point on a circle.
- <u>Arc</u>: the curve between two points on the circumference of a circle
- <u>Intercepted arc</u>: the arc that is between the endpoints of the chords that form the inscribed angle.
<u>Inscribed Angle Theorem</u>
The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.
Therefore:
