Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
30
Is a right angled triangle.
2x0+300 = 900 Solving the equation: 2x0 = 600 So the measures of the angles are: 90 degrees, 60 degrees and 30 degrees.
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
30
A right angles triangle, as one of the angles in the triangle is 90 degrees.
90 degress :P
An isosceles triangle has angles of 75, 75 and 30 degrees.
If 2 of its interior each measure 30 degrees then it is an isosceles triangle
120 degrees.
It is 180 - (29+30) = 180-59 = 121 degrees.
If you mean the ratio of 2,4,6 then the angles are 30 degrees, 60 degrees and 90 degree which in effect is a right angle triangle.
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. == ==
A right angled scalene triangle
If you're referring to the internal angles of a triangle - the missing angle would be 30 degrees. Remember - in a flat triangle - the internal angles always add up to 180. Therefore - add up the angles you know, then subtract that from 180.
