Answer:
a. 72 = 2 x 2 x 2 x 3 x 3
b. 252 = 2 x 2 x 3 x 3 x 7
c. 625 = 5 x 5 x 5 x 5
Step-by-step explanation:
Answer:
2. one angle is 108, and other is 72
3. x is 12
Step-by-step explanation:
the ratio is 3:2.
3x + 2x = 180
5x = 180
x = 36
36 x 3 = 108
36x 2 = 72
so that is why the two angles re 108and 72.
for the last question, 37 plus 41 plus x = 90
37 plus 41 is 78
90 - 78 = 12
so that is why x is 12.
