Answer:
3:10
Step-by-step explanation:
1. Find the total number of students by doing
14 + 6= 20
2. Now make your ratio
6:20
3. To make it in simplest form, divide both sides by 2
6 divided by 2 is 3
20 divided by 2 is 10
4. Your answer is
3:10
So for this, you'll be using the pythagorean theorem to solve for the height.

Solve the exponents to get

Subtract 81 on each side to get

Square root each side, and your answer should be

or 13.23 ft

Answer:
b = 100°
c = 30°
Step-by-step explanation:
b = 100° bc the two angles are supplementary, that is, together they form a straight angle and add up to 180°.
c = 30°
because a + b + c = 180. There's 180° in a triangle.
