Answer:
c it is 91
Step-by-step explanation:
Step-by-step explanation:
STEP 1:
Find a length of third side.
Use the Pythagorean theorem:
STEP 2:
Use the trigonometric functions:
STEP 3:
Use theorem: the sum of the measures of acute angles of the right triangle is 90°.
Example:
We have the length of legs: a = 3, b = 4.
Let c = hypotenuse.
Use the Pyhagorean theorem:
Angle between a and c (β):
Use sine. Therefore b = opposite, c = hypotenuse:
<em>look at the picture</em>
<em>subtract 37° from both sides</em>
i would suggest finding the answer, and then rounding it.
so 0.15 (15%) of 23.77 is 3.5655. So round it to the nearest cent which is 3.56
Answer:
Given: f(x)=\dfrac{1}{9}(x-2)
We need to find the inverse of f(x).
Step 1: Set f(x) = y
y=\dfrac{1}{9}(x-2)
Step 2: Switch x and y
x=\dfrac{1}{9}(y-2)
Step 3: Solve for y, Isolate y
x=\dfrac{1}{9}(y-2)
Multiply by 9 both sides
9x=y-2
Add 2 both sides
9x+2=y
y=f^{-1}(x)
Hence, f^{-1}(x)=9x+2
