The answer would be 54 since there is only 180 degrees in a triangle so you subtract 90 and 36 from 180. You get 54

Answer:
82 is the answer
Step-by-step explanation:
hope it help you
The left triangle is a 30-60-90 triangle so line ST = 2 which means line RT is 4 (double the length of ST).
The right triangle is a 45-45-90 triangle which means RT and RQ are congruent.
So if RT = RQ and RT = 4, then x = 4
He swam 1,800 laps total in 12 weeks. Each week, he swam 150 laps because 1800/2=150 in 5 days. Each day, he swam 30 laps because 150/5=30, in 45 minutes. His average time was 30/45=2/3 At that rate, in one hour, he would swim 2/3*60 = 2/3 x 60 = 40 laps/hour Final answer is 40
