I think m=2... i think..still learning this subject
Is it 5+7+11 ???????????????????????????
<span>Terminal side of -210 is on quandrant 2. Negative angle goes clockwise. So the sin(-210) equal to 1/2. So for each choice, it should be in quandrant 2 and sin should be 1/2. What we do is find the point and draw a right trangle bases on the point and orgin, final solution should be choice 4.</span>
Hi, thank you for posting your question.
This problem can be solved through ratio and proportion which can be applied to similar triangles like that shown in the figure. By ratio and proprotion,
MP/MN = MB/MA
81.9/67.2 = x/(67.2-32)
Thus, x = 42.9
