We know the lenght of the side adjacent to angle A, AC, and we want to know the opposite side, BC. What trig ratio describes the relationship between opposite and adjacent? The Tangent! 

tan (x) = opp / adj
In this case, tan (45°) = BC / 4
To get BC by itself, multiply both sides by 4
4 * tan (45°) = BC

The answer is D

A gardener wants to run a border around the outside of her garden. She plots it on a grid to plan how much she will need. The ga
Kamila [148]
Answer: 16 ft

Explanation:

You can determine the lengths of each segment by subtracting the coordinates of the adjacent points.

1) From (2,5) to (8,5): 8 - 2 = 6

2) From (8,5) to (8,3): 5 - 3 = 2

3) From (8,3) to (2,3): 8 - 2 = 6 (as expected as this is congruent to the first

4) From (2,3) to (2,5): 5 - 3 = 2 (as expected as this is congruent to the second).

The total length of the border or perimeter is equal to the sum of all the sides:

perimeter = 6 + 2 + 6 + 2 = 16

Therefore the answer is 16 ft

Given: AE = 3, CE = 5 and ED is 4 less than EB find EB. Please give a step-by-step explanation. The best answer will receive bra
alisha [4.7K]

Answer:

EB = 10

Step-by-step explanation:

For this problem, you can use the power of a point, in the situation where two secants intersect in the interior of a circle. The formula is as follows:

CE * ED = AE * EB

(This is applied specifically to this problem)

We can substitute the values given,

5 * (x - 4) = 3 * x

simplify,

5x - 20 = 3x

and solve.

2x - 20 = 0

2x = 20

x = 10

Since the value of EB is x, EB = 10.
