If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
Measure it or use trigonometry if the 'included' angle is given.
You don't. It takes more than one side and one angle to determine a triangle. If you have two sides and the angle between them, or one side and two angles, you can do it.
The sum of the three angles of a triangle will always be 180 degrees. So to find the third angle, one must take 180 - 35 - 77. The answer would be 68

If you have angles, use the sine rule: a/sin A = b/sin B = c/sin C a denotes the side, A the angle opposite the side.

The third angle is 93 degrees
90
Add the first two angles together and subtract the total from 180 to find the 3rd angle
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.
Yes it is. A normal, 3:4:5 triangle has a right angle, three different angles, and three different sides. There should be more for you to find.
The third angle is [180-(32+70)] = 180-102 = 78
