Answer:
A) 5 + 2 =7 x 4= 28
B) 8
Step-by-step explanation:
A) 5 x 4 = 20 and 2 x 4 = 8 so you add 20 + 8 and you get 28
B) so 5 x 4 is 20 and there is 8 left over and if you do 2 x 4 you get 8
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
