First you would need to solve x. 2x+x+14+x-38=180 4x-24=180 4x=204 x=51 Now plug in the x for all three angle measures. 2(51)=102 degrees 51+14=65 degrees 51-38=13 degrees Final answer is 102 degrees, 65 degrees, 13 degrees
Since you know that the angles in a triangle add up to 180°, you can solve for x by making it an equation: 2x + x + 14 + x - 38 = 180 4x - 24 = 180 + 24 4x = 204 ÷ 4 x = 51 Now you can substitute x in to the angles 51 × 2 = 102° 51 + 14 = 65° 51 - 38 = 13° I hope this helps!
