The inside angles of a triangle always add up to 180 degrees.If you mean angle a plus angle b equal 85 degrees, then angle c must be 95 degrees.If you mean angle a is 85 degrees and angle b is also 85 degrees, then angle c must be 10 degrees50 degrees :)

Is there an angle whose supplement is equal to its complement?
yes. a + b = 90 degrees: complements: C + D = 180: supplements: a = 5, b = 85, c = 95, d = 85. b & c are supplements. b = d
What is the measure of angle A if angle B is 100 degrees and angle C is 30 degrees?
50 degrees if its a triangle
Httpwww.answers.comQIn triangle ABC angle A equals 17 and angle B equals 100 what is the measure of angle C?
Anglw C is 63 degrees because the 3 interior angles of a triangle add up to 180 degrees
Can an equiangular triangle be scalene?
No. An equiangular triangle is always equilateral. This can be proven by the Law of Sines, which states that sin A / a = sin B / b = sin C / c, where A, B and C are angles of a triangle and a, b and c are the opposing sides of their corresponding angles. If A = B = C, then sin A = sin B = sin C. Therefore for the equation to work out, a = b = c. Therefore the eqiangular triangle is equilateral, and therefore not scalene, which requires that all sides of the triangle be of different lengths.
What is the measure of angle A if angle B is 75 degrees and angle C is a 90 degree angle?
It is a right angle triangle and angle A measures 15 degrees.
What is the third interior angle of triangle?
Let the angles be a, b and c There are 180 degrees in a triangle: 180-(a+b) = c 180-(a+c) = b 180-(b+c) = a
On a triangle if A equals 72 degrees and b equals 47 degrees what c equals?
61 degrees (180 degrees in a triangle)
How do you find the angles of a triangle when you are given ratios?
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.
If angle B measures 42 degrees and angle C measures 27 degrees what is the measure of angle A?
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
Is there an angle whose supplement is equal to its complement?
yes. a + b = 90 degrees: complements: C + D = 180: supplements: a = 5, b = 85, c = 95, d = 85. b & c are supplements. b = d
A ladder should be erected at an angle to the ground of A 35 degrees B 75 degrees C 65 degrees D 85 degrees?
C 65
What is the measure of angle A if angle B is 100 degrees and angle C is 30 degrees?
50 degrees if its a triangle
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals?
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
If angle A in a triangle is 60 degrees and angle B is 20 degrees what is the degree of angle C?
100
How do you determine the third angle of a triangle if 2 angles are known?
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
In the triangle abc the measure of angle a is 3x degrees the measure of b is x degrees and the measure of c is 4x-28 what is the angle of c?
the answer is 68 degrees
What is the formula in triangle?
Angle A + Angle B + Angle C = 180 degrees. If one angle equals 90 degrees then it is a right triangle and the lengths of the sides are in a ratio such that A squared plus B squared equals C squared (Pythagorean Theorem)
