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
The lowest term is
.
Solution:
Given expression is 
<u>To reduce this term to the lowest term:</u>

Multiply the numerator and denominator.

Now, divide the numerator and denominator by the greatest common factor.
Here 150 and 8 both have common factor 2.
So, divide numerator and denominator by 2.



Hence the lowest term is
.
I’m not sure if this is correct but the answer would be 8.75 well that’s what I got hope this helps and if it dead pls give me a thanks
