Question

Someone help and please make sure it’s right

Answer 1

∠A = 36°

Explanation:

Angle opposite 82° = 98° (180° - 82° = 98°)

the sum of all angles in a triangle = 180° so:

180 = 98 + (x + 37) + (x + 47)

180 = 98 +2x +84

2x = -2

x = -1

∠A = -1 + 37 = 36°

Answer 2

D). 36

Explanation:

98 + (x + 37) + (x + 47) = 180

182 + 2x = 180

2x = -2

x = -1

so now we plug it in.

-1 + 37 = 36

hope this helps!
