Choice b. is right because for x=5 will result this fraction undefined bc than for x=5 the denominator will be equal zero
The sum of angles of a triangle is 180°.
48 +(6x -28) +2x = 180
8x +20 = 180
8x = 160
x = 20
∠B = (6x -28)° = (6*20 -28)° = 92°
∠C = 2x° = 40°
___
x = 20
∠B = 92°
∠C = 40°
X + x + x + x - 20 is equivalent to 4x - 20 because you can add the like terms, or the x's.
