What is the magnitude of the gamma angle in triangle ABC?

In triangle ABC, the magnitude of the internal angle gamma is equal to one-third of the angle alpha. The size of the angle beta is 80 degrees larger than the size of the gamma angle. Calculate the magnitudes of the interior angles of the triangle ABC. See more information about triangles or more details on solving triangles.

What is the sum of two acute angles in a right triangle?

In a right triangle, however, one of the angles is already known: the right angle, or the 90o angle. Let the other two angles be x and y (which will be acute). That is, the sum of the two acute angles in a right triangle is equal to 90o. If we know one of these angles, we can easily substitute that value and find the missing one.

What is the length of BD and ad in triangle ABC?

In a triangle ABC, angle ABC = 90 and BD is perpendicular to AC. If BD = 8 cm and AD = 4 cm then find the length of CD? | Socratic

Which angle is perpendicular to the triangle ABC?

In a triangle ABC, angle ABC = 90 and BD is perpendicular to AC.

How to find the sum of all angles in a triangle?

Given the sizes of the 3 sides you can calculate the sizes of all 3 angles in the triangle. use The Law of Cosines to solve for the angles. You could also use the Sum of Angles Rule to find the final angle once you know 2 of them. Sum of Angles in a Triangle. In Degrees A + B + C = 180° In Radians A + B + C = π. Law of Sines

What is the area of the equilateral triangle ABC with sides?

The area of the equilateral triangle ABC with sides of 8 cm = [ (8*8)/2]*sin 60 = 27.71281292 sq cm. By joining the mid points of the three sides you get 4 equilateral triangles of (1/4) the area of the main triangle and the area of each of the 4 minor triangles = 6.92820323 sq cm. Answer.
