For 1st equation: 2(7)+6 = 14+6 = 20 = R.H.S
For 2nd equation: 6(7)-5(6)= 42-30 = 12 = R.H.S.
So, your answer is "YES" for both system of equations.
Answer:
7p
hope this helps
have a good day :)
Step-by-step explanation:
The answer is 69.6 degrees because all of the angles of a triangle always add up to 180 degrees so adding 42 and 68.4 gets 110.4, and then subtracting that from 180 gets 69.9.
