A right angle triangle has a 90 degree angle and two acute angles whereas altogether the three angles add up to 180 degrees.
Using the cosine rule gives the largest angle of the triangle as 91.04179885 degrees or 91.042 degrees rounded to 3 decimal places. So: 91.042-90 = 1.042 degrees
One right angle is 90 degrees. If it's anything else, it's not a "right" angle.
The inner angles of a triangle add up to 180 degrees. 180 - (70 + 30) = 80 degrees.
First drop of knowledge: the angles of a triangle must combine to equal 180 degrees. An obtuse angle is more than 90 degrees, a right angle is 90 degrees, and an acute angle is less than 90 degrees. Because an obtuse angle is present, it is already over 90 degrees. Let's say it is the least possible whole number for an obtuse angle, which is 91 degrees. Two more obtuse angles would put it above 180 degrees, which is too much to be at triangle. Two right angles would still put it above 180 degrees, still too much. The only combination left is two acute angles (in this case, 45 and 44 degrees). Thus, even the lowest of whole numbers for an obtuse angle requires two acute angles, so any other higher number will require the same.
A right angle triangle has a 90 degree angle and two acute angles whereas altogether the three angles add up to 180 degrees.
Total, the triangle has 180 degrees, and each angle has 60 degrees.
Using the cosine rule gives the largest angle of the triangle as 91.04179885 degrees or 91.042 degrees rounded to 3 decimal places. So: 91.042-90 = 1.042 degrees
180 degrees. An equilateral triangle measures 60 degrees at every angle.
A right angle is 90 degrees
Yes, a triangle has a total of 180 degrees of its angles. Since a right triangle has one angle that is 90 degrees, the other two angles much add up to 180-90=90 degrees. 65+25=90.
a right angle equals 90 degrees.
90.
One right angle is 90 degrees. If it's anything else, it's not a "right" angle.
