70 degrees
A right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.
180 - 90 leaves 90 for the other two, and 90 - 20 = 70
180 degrees in a triangle 180 - 90 - 55 = 35 35 degrees
The other acute angle in that triangle is 40 degrees.
60.255 degrees (rounded)
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.)
Since all the angles in a right triangle add up to 180 and we already have 145, this means that the third angle must be 35 degrees.
180 degrees in a triangle 180 - 90 - 55 = 35 35 degrees
It is 90-28 = 62 degrees
It is: 72 degrees
The other acute angle in that triangle is 40 degrees.
67.5 ?
Each interior angle of an equilateral triangle measures 60 degrees
It is: 90 -27 = 63 degrees
The sume of the measures of the three nagles of an acute triangle (or any triangle) is 180 degrees.
acute-angled triangle
That would be an acute scalene triangle.
