Answer:
140r2
Step-by-step explanation:
Sum of opp. interior angles = ext. angle
sum of all interior angle in a trangle = 180 deg
5(x + 3) - 3(x - 2) = 19 That should give you the result you need. The answer will come out to be x = - 1
If you want it to be - 1 to start with, then
2(5x + 3) - 13x + 2 = - 1
Take the common denominator and divide by 3 then youll get 58
