Answer:
B a = 180 -77-60
Step-by-step explanation:
The angles add to 180 degrees since they form a straight line
77+ 60+a = 180
a = 180 -77-60
That would be correct because if x times x =16 than that means that the square root of 16 is 4
Using the equation 2x + y = 4, we get the following graph.
Answer is -11/7 (extra letters)
The answer is B, Because f + e = c, a2 + b2 = c2.
