Since RS and ST are congruent sides, angles SRT and STR will be equal. Also, angles STU (5x) and STR added together equals 180. Therefore angles STU and SRT will also equal 180. All that's left to do is set up the equation and solve. 5x - 30 + 5x = 180.
First you add the 1/4 and 3/4 together forgetting the /4 and adding the 1+3, that makes 4/4 which is a 1 then add that 1 to the 1 and 2 left over to get the answer
You would multiply 2x4 and 3x4 and it would be 8/12 so that leaves you with 4 twelths left.
