If a triangle has angles 35 and 65 degrees, what is the measurment of the third angle? Is it a right triangle?
The three angles of a triangle equal 180 degrees. The third angle is 80 degrees. Therefore, it is not a right triangle.
To find the measurement of the third angle in a triangle, you can use the fact that the sum of all the angles in a triangle is 180 degrees.
In this case, we have two angles: 35 degrees and 65 degrees. To find the measurement of the third angle, subtract the sum of these two angles from 180 degrees.
Third angle = 180 degrees - (35 degrees + 65 degrees)
Third angle = 180 degrees - 100 degrees
Third angle = 80 degrees
So, the measurement of the third angle is 80 degrees.
Now, to determine if the triangle is a right triangle, we need to know the relationship of the angles. In a right triangle, one of the angles is a right angle, which measures 90 degrees. Since we do not have that information, we cannot conclude if the triangle is a right triangle based solely on the given angles.
