Answer:
x = 40°
Step-by-step explanation:
Complementary angles add up to 90° in total measurement.
[tex](2x-50)+(x+20)=90[/tex]
Solve for 'x':
[tex](2x-50)+(x+20)=90\\\\2x-50+x+20=90\\\\2x+x-50+20=90\\\\3x-30=90\\\\3x-30+30=90+30\\\\3x=120\\\\\frac{3x=120}{3}\\\\ \boxed{x=40}[/tex]
Hope this helps.
