The answer is 45°
By determining the angles of triangle ACB (A=30°, B=45°, C=105° (total of 180°)) and knowing that angle 1 correlates to angle 4 ((1)°=(4)°), we can find angle 1, which is 45°, equal to angle 4.
It's actually PEMDAS. P is for parenthesis. E is for exponents. M is for multiplication. D is for division. A is for Addition. S is for subtraction.
Here's an example that includes all of these:
(6-2)²x4/2+6-4
P first.
(6-2) = 4
(4)²x4/2+6-4
Now E.
(4)² = 16
16x4/2+6-4
Then M.
16x4 = 64
64/2+6-4
Next is D.
64/2 = 32
32+6-4
Now A.
32+6 = 38
38-4
And finally, S.
38-4 = 34.

The least common multiple<span> (</span>LCM<span>) of two numbers is the smallest number (not zero) that is a multiple of both.
That being said, 6 would be the LCM. Every number can go into 6 evenly. </span>
