To start out, you can use the 50 degrees. on the opposite side, which is 2, it would also be 50 degrees because they are equal.
to find 1 and 3, you need to remember that a line equals 180 degrees. You can do 180-50 which equals 130 degrees. That is the answer to number 1. It is the exact same for 3.
Answer:
NO.
Step-by-step explanation:
Check if the sides obey the Pythagoras Theorem:-
14^2 = 196
12^2 = 144
5^2 = 25
12^2 + 5^2 = 169 which is not 196, so the answer is NO.
(5 + 3) / (-2 -8) = 8/-10 = -4/5
