A
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.
Step-by-step explanation:
The answer explains itself.
The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are <em>complementary</em> (not supplementary).
The mnemonic SOH CAH TOA reminds you that ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
There will be 360-324 or 36 inches of fringe left over. This is equal to 3 feet of fringe left over.
Answer:
Step-by-step explanation:
Isolate the b from one side of the equation.
<u>First, subtract by 5 from both sides.</u>
<u>Solve.</u>
<u />
<u>Subtract.</u>
9-5=4
2b=4
<u>Divide by 2 from both sides.</u>
2b/2=4/2
<u>Solve.</u>
<u />
<u>Divide the numbers from left to right.</u>
4/2=2
Therefore, the correct answer is b=2.
I hope this helps, let me know if you have any questions.
You have 12 cards numbered as follows: 2,5,8,10,12,15,18,20,10,7,9,11. What is the probability of choosing an even number, given
ANEK [815]
Answer:
7/12
Step-by-step explanation:
Simple:
There are 12 numbers in all and only 7 even numbers
Since there are 7 even numbers the probability of rolling an even number is 7/12.
This means that there are 7 outcomes of an even number
Therefore the probability of choosing an even number
=7/12
