WebFeb 2, 2024 · There are several ways to find the angles in a triangle, depending on what is given: Given three triangle sides Use the formulas transformed from the law of cosines: \cos (\alpha)=\frac {b^2+c^2-a^2} {2bc} cos(α) = 2bcb2 + c2 − a2 So: \alpha= \mathrm {arccos}\left (\frac {b^2+c^2-a^2} {2bc}\right) α = arccos ( 2bcb2 + c2 − a2) WebAn exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees. ⇒ c + d = 180° ⇒ a + f = 180° ⇒ b + e = 180° All exterior angles of a triangle add up to 360°. Proof: ⇒ d + e + f = b + a + a + c + b + c ⇒ d +e + f = 2a + 2b + 2c = 2 (a + b + c) WebTriangle ABC has angle measures A= x°, B= (2x + 10)°, and C= (3x + 2)°. What is the measure of angle A, angle B and angle C? Hint: The sum of the interior angles of any triangle is 180 degrees.° Please explain/show your work. philips l\u0027or barista coffee machine
