Because the total sum of interior angles of a triangle is 180 degrees.
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
It is a scalene triangle and the 3rd angle is 30 degrees.
For any triangle, be it 'Scalene, Equilateral, Isosceles, Right-angled', the sum of the interiod angles is ALWAYS 180 degrees.
The inner angles of a triangle add up to 180 degrees. 180 - (70 + 30) = 80 degrees.
40 degrees

It is generally said to be about 75 degrees Fahrenheit, or about 25 degrees Celsius.
If the angles are x, 3x and 3x+5, the following equation gives x x+3x+(3x+5)=180 -> x =25, and in degrees the angles are 25, 75 and 80.
180 degrees in a triangle 180-70-30 = 80 The other angle is 80 degrees
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
The GCF is 5.
180 - (80 + 60) ie 40
x + (3x) + (x + 55) = 1805x + 55 = 1805x = 125x = 25 . . . 3x = 75 . . . x+55 = 80Check . . . 25 + 75 + 80 = 180 yay!
Yes because there are 3 interior angles in a triangle that add up to 180 degrees
40 degrees
30 degrees
It is a scalene triangle and the 3rd angle is 30 degrees.
