This relationship holds true for all right triangles and is a fundamental property of trigonometry.
The relationship between the sines and cosines of the two acute angles in right triangles is defined by the concept of trigonometric ratios. The sine of an angle is equal to the ratio of the length of the side opposite the angle to the hypotenuse, while the cosine of an angle is equal to the ratio of the length of the side adjacent to the angle to the hypotenuse. The relationship between the sines and cosines can be summarized as follows: the sine of an angle is equal to the cosine of its complement, and the cosine of an angle is equal to the sine of its complement.
This relationship exists because the two acute angles in a right triangle are complementary angles, meaning their sum is equal to 90 degrees. Since the hypotenuse is the longest side in a right triangle and is shared by both angles, the ratio of the length of the side opposite one angle to the hypotenuse is equal to the ratio of the length of the side adjacent to the other angle to the hypotenuse. Therefore, the sine of one angle is equal to the cosine of its complement, and the cosine of one angle is equal to the sine of its complement. This relationship holds true for all right triangles and is a fundamental property of trigonometry.

Apples are on sale at the local fruit stand at 4 lbs. for $2.60. Which equation can be used to find the cost, c, of n pounds of apples?
c = 4
c = .65n
c = 2.60n
c = 8n
Answer:
B ) c = 0.65n
Step-by-step explanation:
To find how much a single pound costs, divide the total cost by the total weight (2.60 ÷ 4). So, the cost (c), equals $0.65 per pound.

2.5 or 5/2
Step-by-step explanation:
Y2-Y1/X2-X1=m
(2-k)/(3-4)=5
(2-k)/-1=5

Answer:
Look down below!
Step-by-step explanation:
Fist, make your inequality:
-x + 5y > -10
5y > x - 10
y = .2x - 2
Now, plug in any value of x to find y!
Ex: x = 5...
y = .2 (5) - 2
y = -1
Your first coordinate could be (5, -1)

Write an solve the inequality. A gym charges a one time sign-up fee of $10.25 and then $5 each time you go. A student can pay up to $135.25. How many times can the student go to the gym?
Answer:
25 visits
Step-by-step explanation:
Given data
One time fee= $10.25
let the number of times visited be x
and the total cost for x visits be y
Hence
y=10.25+5x------------1
for y=135.25
let us find x
135.25= 10.25+5x
135.25-10.25= 5x
125=5x
x= 125/5

Find the square root. 1/16
Answer:
The square root of 1/16 is 1/4=0.25
Step-by-step explanation:
The square root of 1/16 is 1/4.
To find the square root of 1/16, you can take the square root of the numerator and the denominator separately.
√(1/16) = √1 / √16
Since the square root of 1 is 1, and the square root of 16 is 4:
√(1/16) = 1/4
So, the square root of 1/16 is 1/4.
