Question

Please explain Geometry

Answer 1

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 )

d = 24

Answer 2

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.

Hope this helps
