The answer to this problem is 100
Answer:
20
Step-by-step explanation:
sin(28) sin(x)
---------- = -----------
7 5
sin(28)* 5 = 7sin(x)
---------------------------
7
sin(28) * 5
---------------- = sin(x)
7
You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).
sin(28) * 5
sin^-1 (------------------) = x
7
Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)
Hope this helps.

Taking the LHS:

Using identity 1:

Using identities 2 and 3:

Using identity 4:

As, LHS = RHS
Hence proved
Answer:
4/5
Step-by-step explanation:
Slope(m) = (y2-y1)/(x2-x1)
Pick two points on your graph that are closest to clear values. (By that I mean you shouldn't pick points that aren't obvious unless you have to.)
For instance, I see the points (-2,0) and (3,4) to be clear; so we don't have to approximate anything.
You could plug these in in a any order but I'm going to let Point 1=(-2,0) and Point 2=(3,4). So:
m=(4-0)/(3--2)=(4/5)
Slope=4/5
