Answer:
39
Step-by-step explanation:
you do 180 and subtract both values you already have 102 and 39. you get the answer of 39
60 percent because if you divide if you multiply 18 by 100 it gives you 18000 then divide it by 30 it gives you 60
(3x + 5)° + (10x - 7)° = 180°
13x + (-2) = 180
13x = 180 + 2
13x = 182
x = 14
∠QRT = 3 * 14 + 5 = 42 + 5 = 47°
∠TRS = 10 * 14 - 7 = 140 - 7 = 133°
