The measure of the third angle in a right triangle with one interior angle measuring 51.1° is 34.9°.
By definition, all triangles have interior angles that add to 180°. Thusly:
Angle A + Angle B + Angle C = 180°
Also by definition, a right triangle has one angle that measures 90°. Therefore
90° + Angle B + Angle C = 180°
We know the measure of one of our angles, so...
90° + 55.1° + C = 180°
Combine the two known angles...
145.1° + C = 180°
Subtract 145.1° from both sides to solve for C
145.1° - 145.1° + C = 180° - 145.1°
C = 34.9°

Find the third angle of a right triangle if the measure of on of the angles is 68?
The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees
What is the third angle of a right triangle if one of the angles measures 24?
The 3rd angle is: 180-90-24 = 66 degrees
What type of triangle has an angle that measures 20 degrees and and angle that measures 90 degrees?
Any triangle that has an angle measuring 90 degrees is a right triangle.
How many right angles does a right triangle contain?
A Right Angle Triangle contains one right angle.A right angle has a magnitude of 90°, or in radians (pi/2). A triangle has three angles forming the closed shape, the addition of which gives an angle of 180°, or pi radians. With two right angles, the addition of these alone gives 180° (pi radians), and therefore the last angle has a null value. This is impossible and therefore leads to the conclusion that no triangle can have more then one right angle.As the definition of a Right Angle Triangle requires an angle of 90°, and no triangle can have two of these angles a Right Angle Triangle must have exactly one right angle.
Triangle with two 45 degree angles?
It is a right angle triangle
A triangle in which one of the angles measures 90?
A right angle triangle.
What does not have any right angles or angle whose measures are larger than a right angle?
An equilateral triangle, which has 3 angles of 60o.
In a right-angled triangle besides the right - angle one of the angles measures 30 degrees what does the other angle measures?
60 degrees. There are 180 degrees in a triangle.
What possible measures for angle a and angle b with triangle abc is a right triangle with the right angle at c?
'a' and 'b' must both be acute, complementary angles.
If the sum of the measures of two angles of a triangle is equal to the measure of the third angle the triangle must be?
...a right triangle.
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
How can you use ratios of the side lengths to find the angle measures of the acute angles in a right triangle?
By using trigonometry that is applicable to a right angle triangle.
What triangle has one angle that measures 40 degrees one angle that measures 90 degrees and another angle that measures 50 degrees?
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
How do you draw a triangle DEF that angle F measures 90 degrees?
It will be a right angle triangle with a 90 degree angle and 2 acute angles
What conclusion can you make about the angle in a right triangle?
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
What angle Angle of a triangle is equal to the sum of the measures of its two remote interior angles?
A right angle triangle has a 90 degree angle and its other two angles add up to 90 degrees
Does a right angled triangle is one angle always a right angle?
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
