Answer:
If the sinø=7/12, cosø is 
Step-by-step explanation:
We are given sinФ = 7/12
We need to find cosФ
The basic trigonometric functions of right triangle are:


We need values of adjacent and hypotenuse to find cosФ
Using Pythagoras theorem we can find the value of adjacent

We have Hypotenuse= 12 and Opposite = 7 (because
and we are given 
Inserting values and finding adjacent:

So, value of Adjacent is 
Now finding cosФ

Adjacent =
, hypotenuse = 12

So, If the sinø=7/12, cosø is

Answer: y=-3x-4
Step-by-step explanation:
Since we know slope, we can plug it into slope-intercept form to find the y-intercept by using the given points,
y=-3x+b
8=-3(-4)+b
8=12+b
b=-4
Now that we know the y-intercept, we can complete the slope-intercept form.
y=-3x-4
Answer:
they have to be congruent
