As the sum of angles is a triangle is 180°, the third angle is 180-48-19=103°
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
YesAnother Answer:-Yes under certain conditions depending on what type of triangle it is and the measure of the angle givenBut normally two angles are needed to find the third angle in a triangle

Two angles of a triangle add up to 65°. What is the measure of the third angle?
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
The sum of the angles of a triangle is 180 degrees. If the sum of two of a triangle's angles is 148, then the third angle must be 180 - 148 = 32 degrees.
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
The other acute angle in that triangle is 40 degrees.
If two angles of a triangle each measure 55 what is the measure of the third angle?
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
The third angle of an isosceles triangle doesn't have a name.
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
