45 degree angle
In plane geometry the angles in a triangle always add to 180 degrees. Add the two angles you know together and subtract the total from 180. This will give you the third angle.70 + 65 = 135.180 - 135 = 45
It is acute
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
65
Yes. The fourth angle is 115 degrees.

It must be 65 degrees because there are 180 degrees in a triangle. 90+25+65 = 180
57.5 degrees
All triangles are 180 degrees.
Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.
The three angles in a triangle add up to 180. 38 + 27= 65. 180-65=115
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees
Yes because the 3rd angle will be 90 degrees which is a right angle

The triangle with angles measuring 50 degrees, 65 degrees, and 65 degrees is an isosceles triangle. In an isosceles triangle, two of the three angles are equal, making it a special type of triangle. In this case, the two angles measuring 65 degrees are equal, indicating that the two sides opposite these angles are also equal in length.
90 - 25 = 65. The answer is 65 degrees.
Its 2 equal base angles will each measure 65 degrees
