Amayo943,
Remember that with exponents you have to multiply the number of exponets by the same number it's in for example:
In this case you need to know that:
Therefore your answer is "225."
Hope this helps!
The two angles are corresponding angles, so they are congruent (due to the horizontal lines being parallel)
x+15 = 102
x+15-15 = 102-15 .... subtract 15 from both sides
x = 87
1. X=5
2. I think I’m not sure is - 5.04
