How to solve an obtuse triangle

WebThe range of inverse sine is restricted to the first and fourth quadrants. So what this means is using the Law of Sines is only ever going to give you acute angles. If you want to find the obtuse angle, you have to subtract the acute angle from 180 or just use the Law of Sines on the smallest angle to ensure it works. ( 30 votes) Flag Show more... WebFinding area of triangles. To find a triangle's area, use the formula area = 1/2 * base * height. Choose a side to use for the base, and find the height of the triangle from that base. Then, …

WebIn this triangle we know the three sides: a = 8, b = 6 and c = 7. Use The Law of Cosines (angle version) to find angle C : cos C = (a2 + b2 − c2 )/2ab = (82 + 62 − 72 )/2×8×6 = (64 + 36 − 49)/96 = 51/96 = 0.53125 C = cos−1 (0.53125) = 57.9° to … WebWhen using similar triangles, their sides are proportional. If two triangles have two congruent angles, then the triangles are similar. So, if you have a 30-60-90 triangle then the sine ratio is defined as the ratio of the length of the side opposite to the length of the hypotenuse. WebThe sum of the angles in a triangle is 180o: a + b + c = 180 In this case, the average of a and b is 75: (a + b)/2 = 75, then multiply both sides by 2 (a + b) = 150, then substitute into first equation 150 + c = 180 c = 30 Report an Error Example Question #2 : How To Find An Angle In An Acute / Obtuse Triangle dzida the forest
