50 degrees. 45 and 85 add up to 130 and in a triangle there are 180 degrees in total in a triangle. So subtract and you get 50 degrees.

40 degrees ! The internal angles of any triangle always total 180 degrees. Since you already know two angles (50 & 90) - the difference is 40.

In a right triangle, all the angle measurements together add up to be 180 degrees. And since it is a right triangle, one of the three angles is 90 degrees so if you are given one of the angles other than the right angle's measurements, you can find the angle measurements. Here's an example: There is a right triangle. One angle measures to be 45 degrees. What is the missing angle measure? Well we know that one angle must be 90 degrees and the other (as we were told) is 45 degrees. 90+45=135 and we know that a right triangle=180 degrees total and 180-135= 45. The missing angle is equal to 45 degrees! hope this makes sense and it helped.

In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95

50 degrees. 45 and 85 add up to 130 and in a triangle there are 180 degrees in total in a triangle. So subtract and you get 50 degrees.

If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.

The total sum of all angles in any triangle is 180 degrees.

The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.

Total, the triangle has 180 degrees, and each angle has 60 degrees.

70 degreesA right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.180 - 90 leaves 90 for the other two, and 90 - 20 = 70

The internal angles of a triangle always total 180º. So 180º - (15º + 85º) = 80º.

40 degrees ! The internal angles of any triangle always total 180 degrees. Since you already know two angles (50 & 90) - the difference is 40.

The measure of each base angle in an isosceles triangle can be calculated by dividing the total angle sum by the number of base angles, i.e., (180 - vertex angle) / 2. In this case, each base angle of the isosceles triangle would measure (180 - 38) / 2 = 71 degrees.
