WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. Webuse The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle. Example 1 In this triangle we know: angle A = 49° b = 5 and c = 7 To solve the triangle we need to find side a and angles B and C. curl equivalent in pythonWebTo find cos θ, we need the adjacent side and the hypotenuse. Here, the adjacent side = 8. But we are not given the hypotenuse. To find this, we use Pythagoras theorem: hypotenuse 2 = opposite 2 + adjacent 2 = 6 2 + 8 2 = 100 hypotenuse = √100 = 10 Therefore, cos θ = Adjacent/Hypotenuse = 8/10 = 4/5 cos θ = 4/5 curl command to check ssl
