-5.8 + (-2.5) = -8.3
since both the number are negative you simply add the numbers and use the negative sign.
Answer:
false
Step-by-step explanation:
y>-2x-2
3>-2(-2) -2
3>4 -2
3>2
y< 3
3< 3
Using sine law:
9/sinc = 15/sin22
sinc = 9sin22 / 15 = 0.225
so c = sin^-1(0.225) = 12.99 degrees ~~ 13 degrees
if B was required:
B = 180 - C - A ~~ 145
I just did this a few seconds ago and the correct answer is 78. The check above the number is green which means its correct.
