Answer:
sin 4/9 if cos is 3/5
Step-by-step explanation:
A cosine function is equivalent to the adjacent side divided by the hypotenuse , from SOH-CAH-TOA.
So, our adjacent side can be 3 , and the hypotenuse can be 5.
Then, we can use the Pythagorean theorem (a^2 + b^2 = c^2) to find the missing side length.
3^2+b^2=5^2
9+b^2 =25
b^2=16
b = 4
We found our three sides: 4, 5, and 9.
We know from SOH-CAH-TOA that the sine function is equivalent to the opposite side length divided by the hypotenuse length. So:
sin θ = 4/9
This is an Inverse.
Final Answer : A
This is because each part (the hypothesis and conditional) were reversed.
Y=x-4
From this we plug in the answer to find the y value!
For example y=3-4=-1 A.) would be incorrect!
Y=3-4=-1 B.) would be incorrect!
C.) y= -3-4=-7 while it’s SUPPOSE to be 7.
D.) y= -3-4=-7 and y value is -7
Correct answer: D!
