For angle A, you need to do 180-130 which is 50
for angle B, you need to do 180- 90 - 50 which is 40
for angle C, you need to do 180 - 60 - 40 which is 80
If you want me to explain you with further details with how exactly I got those answers and how I knew what to do, then ask me.
For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,
0.47 degrees * 60 minutes per degree= 28.2 minutes
Now you have 17 degrees 28.2 minutes
but you can replace fractions of a minute with seconds
0.2 minutes * 60 seconds per minute= 12 seconds
So the answer for
17.47º is equal to 17º 28' 12".
I hope this helps.
