<span>The reference angle is closest to the x-axis.
I will assume the above is 7pi/6. That would be a reference angle of pi/6, and the sin in the 3rd quadrant is negative, so the sin theta = - 0.5</span>
41/10
4.1 = 4 1/10 = 41/10
Answer:
9
Step-by-step explanation:
Area of a triangle=(base*height)/2
1) Input the values
54=(12h)/2
2) Multiply both sides by 2
54*2=(12h/2)2
108=12h
3) Divide both sides by 12
108/12=12h/12
9=h
I hope this helps! Please comment if you have any questions.
