Measure of angle A=180- Measure of angle C + Measure of angle B
2x=180-(90+3x)
2x=180-90-3x
+3x. +3x
5x=180-90
5/5x=90/5
x=18
Measure of angle is
A= 2x
A=2(18)
A=36
Measure of angle B =
3x
3(18)
54
Simply, Measure of angle A is 36, Measure of angle B is 54 and measure if angle C is 90
Answer:
Step-by-step explanation:
Take the derivative of 2x/(x+2) using the quotient rule.
you get 4/(x+2)^2. The slope of the tangent line is this functions value at 2.
4/(2+2)^2 = 1/4
Now solve for b when by plugging x and y into y = 1/4x + b
1 = 1/2 + b
b = 1/2
The tangent line is y = 1/4x + 1/2
i think D is the answer which is correct .
The given lines are perpendicular
Step-by-step explanation:
if Two lines are perpendicular then their slopes are
m
Where m₁ is slope of first line and m₂ is the slope of second line.
Since the lines are in slope-point form the standard form is:

where m is the slope
The slope of first line y= -9/5x + 1/5 is: m₁ = -9/5
The slope of second line y= 5/9x + 2/9 is: m₂= 5/9
So, m
i.e 
So, The given lines are perpendicular
