Answer:
A triangle's total is 180 degrees. 90 is a right angle. 20 is the angle for A. That would mean the value of 90+20=110. 180-110=70 B is 70
The value of n would be 2.2. You would find this by distributing -6.5 into the parentheses which gives you -6.5n+32.5=18.2. Subtract 32.5 from both sides and you have -6.5n=-14.3. Divide -6.5 on both sides and you get n=2.2
