Answer:
the answer would be -4
Step-by-step explanation:
14 - 3(6) = -4
It is C because a straight line is 180 degrees, eliminating A. That being said, the “bigger angle” is 12x-30 because it is obtuse. B and D are both acute, while C is obtuse. You can also find the answer by finding x as in the equation 3x+(12x-30)=180. By simplification, x=14. So, plugging it in, 12(14)-30=138.
Answer:
25
Step-by-step explanation:
The longest side is 12.
The two other sides of the triangle=
=(9+36)square rooted=45 square rooted is about 6.7.
6.7*2=13.4
13.4+12=25.4
25.4 rounded to the nearest unit is 25.
