If one the angles of a right triangle is 30 degrees what are the other two angles?

Total sum of angles in a triangle is equal to 180 degrees . Right triangle has a 90 deg. angle so 180-90= 90-30 = 60. The three angles are 90 60 and 30 degrees. == ==

What is a right scalene triangle?
a triangle that has a right angle and the other two angles are diffrent ex: angles= #1. 90 degrees/#2. 35 degrees/#3. 55 degrees
What does a right triangle means?
Every triangle has three interior angles which total 180 degrees. A right triangle has one of the angles as 90 degrees.
Can a triangle have 2 right angles?
No, a triangle has to have a combined sum of the 3 angles at 180 degrees, a right angle is 90 degrees. It is impossible to have a 90,90,0 triangle
Can a right triangle be an obtuse triangle?
No, in a right triangle, the other two angles are complementary so they are both less than 90 degrees.
How many obtuse and acute angles can be in a right triangle?
In a right triangle, one of the angles is already given - 90 degrees. Since the angles of a triangle must add up to 180 degrees, the other two must always add up to 90, so that after you add the right angle, the sum is 180. So both of the other angles have to be less than 90. That is, they both must be acute. So there can be NO obtuse angles in a right triangle. There are EXACTLY two acute angles in a right triangle.
What are the angles of a right isosceles triangle?
The two other angles are 45 degrees each. The three angles of every triangle always add up to 180 degrees. -- A right triangle is a triangle that has a right angle in it. -- A right angle is 90 degrees. -- That leaves 90 degrees for the other two angles in the right triangle. -- If it happens to be isosceles, then the other two angles are equal. -- Those must both be 45 degrees.
Are the two acute angles of a right triangle complementary?
Yes. Compementary angles total 90 degrees. In a right angled triangle the right angle uses 90 of the 180 degrees in a triangle, leaving 90 degrees for the other two angles.
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.)
What of kind of angles are the other two angles of the triangle?
If it is an equilateral triangle all the angles would be 90 degrees or right angles
What are 3 angles in a right triangle?
All the angles of a triangle add up to 180 degrees. In a right triangle one of the angles must be 90 degrees and the other two can be any combination that adds to 90, such as 30 degrees and 60 degrees.
How can you tell if three numbers equal a right triangle?
A right triangle is a triangle that has one 90 degree angle, and 2 other angles. Some special ones are 45-45-90, and 30-60-90. The sum of the angles in a triangle will always = 180 degrees. Since we know a triangle has 3 angles, and in particular, a right triangle has a 90 degree angle. We can say 180 degrees - 90 degrees = the other 2 angles. Add the other 2 angles in your triangle. Usually one is given as 90 degrees, or has a small square mark in the corner of the triangle to indicate that it is a right triangle. Once you add the other 2 angles, see if they add up to 90 degrees. If they do, you have a right triangle. If they do not, you either do not have a right triangle OR your triangle is broken and all 3 angles do not add up to 180 degrees.
If the angles in a triangle are 30 degrees 60 degrees and 90 degrees is called what type of triangle is it?
A right angles triangle, as one of the angles in the triangle is 90 degrees.
Is a right triangle an equilateral triangle?
No. Within a triangle, the sum of all of the angles must equal 180 degrees. All three angles are acute (60 degrees) in an equilateral triangle, while only two are in a right triangle, the other being a right angle (90 degrees). There obviously could not be three right angles (270 degrees).
What is a right scalene triangle?
a triangle that has a right angle and the other two angles are diffrent ex: angles= #1. 90 degrees/#2. 35 degrees/#3. 55 degrees
Is a right triangle a scalene?
a triangle that has a right angle and the other two angles are diffrent ex: angles= #1. 90 degrees/#2. 35 degrees/#3. 55 degrees
How do you find angles to a right triangle?
You cannot. The other angles of a right triangle can have any values between 0 and 90 degrees as long as the two of them sum to 90 degrees.
Why does the acute angles in an isosceles right triangle always measures 45 degrees?
The question lists three facts: "triangle", "right", and "isosceles". Each fact carries important information. -- "triangle" ... The three angles in any triangle always add up to 180 degrees -- "right" ... One angle in a right triangle must be a right angle = 90 degrees. That leaves the other 90 degrees for the other two angles to share. -- "isosceles" ... Two of the angles in an isosceles triangle are equal. If there are 90 degrees to share between them, then each of them is 45 degrees.
