Answer:
csc (- Ф) = -29/20
Step-by-step explanation:
We know that:
csc Ф = 1/ sinФ ................. equation 1
csc (- Ф) = - csc Ф .............equation 2
Given that:
sin Ф = 20/29
Using equation 1:
csc Ф = 1/ (20/29)
csc Ф = 29/20
using equation 2:
csc (-Ф) = - csc Ф = -29/20

Answer:
Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.
9x+3y = 36
3y= - 9x + 36
y = -3x + 12
The slope, m = -3
------------------
The slope of lines parallel is the same.
The slope of lines perpendicular is the negative inverse, m = +1/3
----------------
Use y = mx + b and the point (1,2) to find b.
2 = (1/3)*1 + b
b = 5/3
The equation is y = (1/3)x + 5/3 (slope-intercept form)
x - 3y = -5 (standard form)

180-160= 20 therefore the answer should be 20 degrees.
If angle4 and angle8 are verticle and that means they probably have the same number of degrees so
3x=x+40
3x-x=x-x+40
2x=40
2x/2=40/2
x=20
if it's not correct apologies
