Can I get some help solving this

Answer:
70 degrees
Step-by-step explanation:
The sum of the degrees of angels in a triangle is always 180degrees. So now you know F = 20degrees and D is a right angel meaning it is 90 degrees, all you have to do is use 180 - 20 - 90 = 70degrees
Answer: 60
Step-by-step explanation: 20 multiply by 3 because you 20 degrees and you have 3 sides so multiply then you get the answer.
