2 and 3 are both 58 as well. For 4 do 180-58 because a straight line is 180 degrees.
Step-by-step explanation:
So i will try to explain it:
Scientists in the past invented this formula and theory of sines:

So the only thing is to put the given numbers into this formula :)
The task that i've just done is like this:

a is the numerator,that is delighted in the triangle,well its transparent.
What about denominator?
Here is the tip:
opposite to A- side angle-a has to be put into sin(a)
sin- how to calculate?
Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

one of this numbers might be unknown in that case solve by proportion(equation).
Carefully contemplate my answer in the media.
I hope you understood.
Good luck!

Answer:
The equation of a line parallel to the line and passing through (1, -1) is:
Step-by-step explanation:
Given the line
y = -3
We know that the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
Thus, the slope of the equation y=-3 will be m = -3
We know that the parallel lines have the same slopes.
Thus, the slope of the parallel line will also be -3.
Thus, using the point-slope form to find the line equation is

substituting the values m = -3 and the point (1, -1)
y-(-1) = -3(x-1)
y+1 = -3x+3
y=-3x+3-1
y=-3x+2
Thus, the equation of a line parallel to line and passing through (1, -1) is:
