Solve this please and thank you​

Answer 1

X = 70

Explanation:

`x + 30 + 2x = 90 \\ 3x - 30= 90 \\ x - (30)/(3) = (90)/(3) \\ x - 10 = 30 \\ Add 10 to \: both \: sides: \\ x-10+10=30+10 \\ Simplify \: the \: arithmetic: \\ x=30+10 \\ Simplify \: the \: arithmetic: \\ x=40`

Answer 2

∠ x = 20°

Explanation:

Complementary angle sum to 90° , so

2x + x + 30 = 90°

3x + 30 = 90° ( subtract 30 from both sides )

3x = 60° ( divide both sides by 3 )

x = 20°
