Answer:
The answer is 14.
Step-by-step explanation:
Since all of the angles of a triangle add up to be 180, then all you have to do is add the 2 angles together that you have and subtract that number from 180. For example 141+25=166, so, 180-166=14. 14 would be the measure of the third angle.
12a-9a>-12+6
3a>-6/:3
a>-2
ok so the two other ways are- 6:2 and 9:3
And the second part- 5
5 x 5 = 25
4 x 2 = 8
25 + 8 = 33 cm^2
