To get this equation you have to perform KCF which stands for Keep Change Flip. KCF is only to be used for division fraction problems. KCF means you Keep the first Fraction, then change the division sign into a multiplication sign. and last flip the last fraction.
35 + 52 + 3(x + 2) = 180 87 + 3x + 6 = 180 ( add the like terms and use distributive property) 93 + 3x = 180 -93 -93 3x = 87 ÷3 ÷3 x = 29 ( the sum of all triangle angles is 180)
