Subtract 4 from both sides and then your answer should be 13.2=h
I only (sort of) know 3 and 4
3. Andle 1 is an example of an angle bigger than

I don't know what you call it.
4. If you have a straight line, both angles (or more) added up need to be

so if angle 1 is 129, 180-129=51
angle 2 is

If 1 is what is the relationship between the two angles, then maybe the answer is that they both added up need to be 180 degress (?)
And 2 is probably the same as 3 but with angle 2, angle two is an example of an angle smaller than 90 degrees
Answer:
4
Step-by-step explanation:
20 x 4 = 80
so 1 per 20 minuets,and 4, 20 min. magazines would mean he needs 4 to make it to 80
To get the answer you need to multiply 1,000 by 7.15 then move your decimal to make it accurate and you should end up with 7150
6/15 and 12/18 are ratios of 2/3
