WebFind the angles of the triangle. Solution Let ∠ACX be the exterior angle of triangle ABC at C such that ∠ACX = 80 o. Clearly, ∠A and ∠B are the interior opposite angles as shown in the figure. It is given that ∠A : ∠B = 3 : 5. Therefore, let ∠A = 3x o and ∠B = 5x o ∠ACX = ∠A + ∠B ⇒ 80 o = 3x + 5x ⇒ 8x = 80 o ⇒ x = 10 o WebThese O-rings are commonly used to create multidirectional seals between two parts in power transmission assemblies, hydraulic cylinders, and pneumatic cylinders.
