B = 3A

C = B-50 = 3A-50

A+B+C = 180

(A) + (3A) + (3A-50) = 180

7A = 230

A = 230/7 = 32 and 6/7

B = 690/7 = 98 and 4/7

C = (690-350)/7 = 48 and 4/7

Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.

The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees

simple... first we know that a triangle has a sum of 180 degrees therefore you add the two known angles then subtract their sum from 180 which gives you the measure of the third angle

Two triangles are considered to be similar if for each angles in one triangle, there is a congruent angle in the other triangle.Two triangles ABC and A'B'C' are similar if the three angles of the first triangle are congruent to the corresponding three angles of the second triangle and the lengths of their corresponding sides are proportional as follows: AB / A'B' = BC / B'C' = CA / C'A'

Well, first of all, the angle sum of a triangle is 180o therefore all three angles must equal that.You will most likely get given degree of two angles and will be left with an unknown one. This will be worked out by:Adding the two angles together = _______Subtract that answer by the angle sum of a triangle 180o.That's your answer...hope this helped :)

The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).

A triangle is a three-sided figure with three angles, two or three of which (depending on the triangle) must be acute angles. The sum of all of the angles has to equal 180° - no more, no less. An acute angle is an angle of less than 90°. If one of the angles of a triangle is 90° or more (it is a right angle or obtuse angle) the SUM of the other two angles cannot exceed 180° minus the degree of the first angle. Therefore the two remaining angles must be less than the first angle, which means that they have to be acute angles.

If its a right angle triangle then the second acute angle is 62 degrees

Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.

The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.

The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
