Question

line AB is parallel to line CD, the measurement of angle A=2x-25, and the measurement of angle C=x+5. find the value of x. show work and explain your reasoning.
joseph
m<A congruent to m<C. 2x-25=x+5, 2x=x+30, x=30, 2(30)-25=35 and (30)+5=35
josef
m<A congruent to m<C. 2x-25=x+5, 2x=x+30, x=30. i forgot what the rule is though sorry
kim
M<A=M<C. 2X-25=X+5. X=30
