'a' and 'b' must both be acute, complementary angles.
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
As we know that all angles of a triangle = 180 degrees So, Angle A + Angle B + Angle C = 180 degrees So, 100 + 17 + x = 180 Angle C = 180 - 117 Angle C=63 degrees
A = 18.1 degrees B = 54.3 degrees C = 107.6 degrees

A = 60 B = 20 C = 140 This can have a large number of answers.
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B

In right triangle ABC, angle C is a right angle, AB = 13and BC = 5 What is the length of AC? Draw the triangle to help visualize the problem.
'a' and 'b' must both be acute, complementary angles.

It can be but need not be.
Is angle C 90 degrees or 80 degrees?
It is a scalene triangle

This is called an isoceles triangle. An isoceles triangles is when two angles equal.
Triangle ABC is congruent to triangle XYZ if AB=XY, BC=YZ, and CA=ZX. Also angle A=angle X, angle B=angle Y, and angle C= angle Z.
