For any point to be in the first quadrant, it must have a positive "x" value and "y" value.
If x = 1 then y = 2, a point with both x and y positive values which would be in the First Quadrant.
Answer:
57°
Step-by-step explanation:
ALL angles in a triangle add up to 180°
SO, if we know the sum of two angles which is 123° (why: 33+90=123), all we have to do is subtract this number from 180 to get the measure of the 3rd angle. Which in this case is 57°

This is a proportion problem that involves cross-multiplication
Set your problem up like so:

=

Now cross multiply
2,000 x 3 = 6,000
now you're left with 5x = 6,000
Now divide by 5 on both sides
Answer is 1,200
Both the top and bottom numbers would have the same scale (ratio) in order to be a proportion.
Find the scale of the top numbers:
18/12 = 1.5
The top numbers have a scale of 1.5 so the bottom numbers also have a scale of 1.5
Multiply the known bottom number by the scale:
M = 34 x 1.5 = 51
