Question

Math home work I have two questions

Answer 1

29

Explanation:

The total degree of a triangle is 180 so

(69 + 53) + 2d= 180

122 + 2d= 180

2d= 180-122

2d= 58

Divide both side by 2

which 29

BUT

i dont really understand if the 2 was the multiple or it just "2d"

in that case "2d" would be 58.

Answer 2

2d = 58 (If you are just finding d then d = 29)

Explanation:

69 + 53 = 122

180 - 122 = 58
