Answer:
d = 24
Explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, hence
2d + 2d + 2 = 98
4d + 2 = 98 ( subtract 2 from both sides )
4d = 96 ( divide both sides by 4 )
Answer: Since the angle of 98° is supplementary the other side of it would be 82°.
Now that you have the third angle of the triangle you use the equation 180 = 4d + 84 (A triangle has 180°) which would be 24 = d when solved.
