Copy this for part A & B, the x-axis is (1.5,0) the y-axis is (0,1)
Answer:
The length of x in the simplest radical form with a rational denominator will be:
Step-by-step explanation:
Given
hypotenuse = 5
angle Ф = 60°
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 60°
adjacent of 60° = x
hypotenuse = 5
so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation
cos Ф = adjacent / hypotenuse
so


switch sides

Multiply both sides by 5

Simplify

Therefore, the length of x in the simplest radical form with a rational denominator will be:
Answer:
y=x-2
Step-by-step explanation:
set up in y1-y2/x1-x2
2 - (-2)/4 - 0
4/4 = 1
so x=1 and the y intercept is -2
so the answer is C
301 is the correct answer:)
