How to solve an obtuse triangle

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 WebTo solve the triangle we need to find side a and angles B and C.

WebIn an isosceles triangle, there are two base angles and one other angle. The two base angles are equal to each other. So say you have an isosceles triangle, where only two sides of that triangle are equal to each other. And then you have 36 degrees as one of your base angles. The other base angle will equal 36 degrees too. 36 + 36 + x = 180 degrees chinese food penfield ny https://ryangriffithmusic.com

WebIn a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. 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 …
