smallest angle --- x
one of the others --- 2x
third angle = x+2x = 3x
thus:
x + 2x + 3x = 180
carry on
in a triangle one angle is twice of other and their sum is the third angle .the angles are
2 answers
assuming you're working in degrees . . .
the three angles sum to 180 degrees
A = 2B
A + B = C
A + B + C = 180
then substitute
the three angles sum to 180 degrees
A = 2B
A + B = C
A + B + C = 180
then substitute
