Answer:
sin x = 3/5
cos y = 3/5
sin x and cos y are equal
Step-by-step explanation:
First we need to find the length of the hypotenuse
We can use the Pythagorean theorem
a^2+ b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 +8^2 = c^2
36+64 = c^2
100 = c^2
Taking the square root
sqrt(100) = sqrt(c^2)
10 = c
The hypotenuse is 10
Since this is a right triangle we can use trig functions
sin x = opp side/ hypotenuse
sin x = 6/10 = 3/5
cos y = adj / hypotenuse
cos y = 6/10 = 3/5
sin x and cos y are equal
The answer would be 92 because 21-3*5+2 would be the equation
Answer:
y = 6x + 8?
Step-by-step explanation:
The starting equation was unclear but if its perpindecular, flip the given slope. For example, if the slope was 3/4, its perpindecular slope would be 4/3.
Answer:
B is 6.
Step-by-step explanation:
We are trying to find a value for 
such that:
is true for every 
.
So let's choose 
:
Divide both sides by -8:
Note: I didn't want to choose y to be 0 because the value of B would disappear from the equation. So you should be able to have chosen any x and y except for y=0 to solve the equation for B.
Check:
So let's check and use foil to multiply out the right hand side.
There was a 2 in front of that multplicapltiation:
This is exactly what we have on the left hand side of your given equation.
Answer:
2 / 36 = 1/18
Step-by-step explanation:
there are 2 ways to get 3
1 then 2 or 2 then 1 , 2 out of a possible 36 outcomes
