Question

I’ll mark you if you’re right:)

Answer 1

Answer: z=74 , x=6

Explanation:

Z = 74

12x+34=180-74

12x=72

x= 6

Answer 2

x=6

z=74

Explanation:

z and 74 are vertical angles and vertical angles are equal

z = 74

74 and 12x+34 are supplementary angles since they form a line. Supplementary angles add to 180.

74+ 12x+34 = 180

Combine like terms

12x+108 = 180

Subtract 108 from each side

12x = 180-108

12x = 72

Divide by 12

12x/12 = 72/12

x =6
