Two of the angles in a triangle measure 50° and 27°. find the measure of the third angle.

The sum of the angles in a triangle is 180°. So...

50° + 27° + x = 180°

77° + x = 180°

Subtract both sides by 77°:

x = 103°

The measure of the third angle is 103°.

Step-by-step explanation:

Divisor = -2n = -2 * 6 = - 12

Dividend = 3 + ( 4 * 6 - 6) = 3 + 18 = 21

Now

21 / -12

dividing numerator and denominator by 3

= - 7 / 4
