3
2,-8
Step-by-step explanation:
this should be the two answers
Law of cosines:
a^2 = b^2 + c^2 -2 *b*c*coa(a)
a^2 = 60.5^2 + 257^2 - 2*60.5*257*cos(31)
a^2 = 3660.25 + 66049 - 2 *60.5 * 257 * 0.857167
a^2 = 3660.25 + 66049 - 26655.33
a^2 = 43053.92
a = SQRT(43053.92)
a = 207.49 = 207.5 feet.
The answer is A.
Answer:
The answer is B
Step-by-step explanation:
4 + 3x = 12
3x = 12 - 4
