Question

I’m not good at math help.

Answer 1

Answer is x= 30

Explanation:

`2(3x + 36) + 2(54) = 360 \\ vertically \: opposite \: angles \: are \: equal \\ and \: sum \: of \: all \: angles \: in \: \: a \\ \: circle \: is \: 360 \: degrees. \\ taking \: out \: 2 \: which \: i s\: common \: \\ 2(3x + 36 + 54) = 360 \\ dividing \: by \: 2 \: on \: both \: sides \: we \: get\\ 3x + 90 = (360)/(2) \\ 3x + 90 = 180 \\ taking \: out \: 3 \: which \: is \: common \\ 3(x + 30) = 180 \\ dividing \: by \: 3 \: on \: both \: sides \: we \: get \\ x + 30 = (180)/(3) \\ x + 30 = 60 \\ x = 60 - 30 \\ x = 30`

Answer 2

x = 30°

Explanation:

Angles on a straight line add to 180° so

3x + 36 + 54 = 180

( Simplify )

3x + 90 = 180

( Minus 90 from both sides to isolate 3x )

3x = 90

( Divide both sides by 3 to isolate x )

x = 30
