Answer:
see explanation
Step-by-step explanation:
Given
2cosΘ -
= 0 ( add
to both sides )
2cosΘ =
( divide both sides by 2 )
cosΘ = 
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ =
(
) = 
OR
Θ = 2π -
= 
solutions are Θ =
, 
Answer:
4
if there are 360 degrees worth of pie then we just divide 360 by 90 getting 4
Step-by-step explanation:
Answer:
Slope = 4
Step-by-step explanation:
This is an equation of a line in the format y = mx + b
Lets match the two equations vertically to see which term is which
y = mx + b
y = 4x - 3
m is the slope, and it matches with the term "4"
That means that 4 is the slope
Parts of y = mx + b
- y : output
- m : slope
- x : input
- b : y - intercept

Answer: 9x - 1 = 9(2) - 1 = 17
Step-by-step explanation:
m∠ABD = m∠ABC + m∠CBD
87 = 9x -1 + 6x + 58
87 = 15x + 57
30 = 15x
2 = x
Not really because there only three but u might get red thought
