How many perpendicular lines must be drawn in a triangle to prove the Law of Sines?..is it 2, 1,0, or 3..Explain

We show 1 to distinguish a vertex, but with laws of supplementary the answer is 2.

Step-by-step explanation:

2

Step-by-step explanation:

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
