    |dw:1357131979991:dw| AD//BC So m<C and m<D are allied angles. Sum of allied angles=180 2x+5+3x-199=180

    Lemme show you another example.|dw:1357132536739:dw| So here we have to find a and b Sum of allied angles=180

    So, a+113=180 and b+54=180 Solve for a and b :)

    Solve the equation You have two parallel lines cut by a transversal Angles C and D are same side interior angles which add up to 180 2x + 5 + 3x - 199 = 180 Combine like terms 5x - 194 = 180 Add 194 to both sides 5x = 374 Divide both sides by 5 x = 74.8 m<C = 2x + 5 = 2(74.8) + 5 = 154.6 m<D = 3x - 199 = 3(74.8) -199 = 25.4
