Start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.

Find the missing side length of the right triangle.

Tomtit [17]

This is just some pythagorean theorem, or a^2 + b^2 = c^2. We have a and b, which is 9 and 12, and we need to find c. To find c, we need to first square those, giving u 81 and 144. Now, we need to add them, giving us 225, meaning c^2 = 225. However, we need to find c on its own, so we have to find the square root of 225. That would be 15.

Answer:

$A = \dfrac{7}{2}\pi~cm^2$

Step-by-step explanation:

There is a formula for the area of a sector given the radius and the angle measure.

$A = \dfrac{n}{360^\circ}\pi r$

n = angle measure

r = radius

$A = \dfrac{140^\circ}{360^\circ}\pi \times (3~cm)^2$

$A = \dfrac{14}{36}\pi \times 9~cm^2$

$A = \dfrac{7}{18}\pi \times 9~cm^2$

$A = \dfrac{7}{2}\pi~cm^2$

Bob sees a very tall white pine tree. He estimates that the angle of elevation from him to the top of the tree is 77°

vlabodo [156]

Answer:

86.63 ft

Step-by-step explanation:

The tangent relation applies.

Tan = Opposite/Adjacent

tan(77°) = (tree height)/(20 ft)

tree height = (20 ft)·tan(77°) ≈ 86.63 ft

_____

<em>Additional comment</em>

It is somewhat problematic for Bob to see the top of a white pine tree at that angle of elevation. His view would likely be obscured by the branches of the tree.

Greg has to carry 191 apples from a farm to the market. how many baskets will need, given that each basket can hold 42 apples?

191 / 42 = 4.5.....so Greg is gonna need 5 baskets....but the last basket is only gonna be half full.
