Answer:
The sine and cosine are complementary functions.
Step-by-step explanation:
In a right angle triangle, the two angle angle are complementary.
This means they add up to 90 degrees.
One special property of the right angle triangle is that, the sine of angle is equal to the cosine of its complement.
On the unit circle we can also create a special right angle triangle with its hypotenuse being one unit.
The complementary property still applies to this right angle triangle.
Answer:
0.07%
Step-by-step explanation:
This equation is solving for what percentage of 100 kg is 0.07 kg.
1. Set up the equation
=
0.07 kg out of 100 kg is equal to x out of 100 because x represents the percentage and percentages are out of 100.
2. Solve by cross multiplying
100x = 7
3. Solve for x by dividing both sides by 100
x = 0.07
The answer is 0.07%
Answer:
It's not 2 sorry about that
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
Let PS = x and RP = x-5
Using Pythagorean theorem on the two smaller rt triangles formed,
6^2 + x^2 = (ST)^2
6^2 + (x-5)^2 = (RT)^2
Now use Pythag on big triangle and sub in above values:
(2x-5)^2 = 6^2 + x^2 + 6^2 + (x-5)^2
Multiply out and simplify to
x^2 - 5x -36 = 0
Factor the quadratic: ((x-9)(x+4)=0 Therefore x=9 or x=-4. We may disregard the negative answer so x = 9. So PS is 9 and RP is 4.
Therefore entire hypotenuse is 4 + 9 or 13.
Answer:
negative 3.6
Step-by-step explanation:
-3=x/1.2
x=-3.6
the answer is negative 3.6
