A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
Answer:

Step-by-step explanation:
We have been given a graph of the function f(x).
Now we need to use that graph to find the equation of the graph and match with the correct choice from the give choices:




We see that graph has end points in opposite direction then the degree of polynomial must be ODD.
Available degrees are 3 and 4. Degree 3 is odd so it is choice B or C.
Only
satisfies the given points from graph.
Hence correct choice is
.

Answer: 6.89
Step-by-step explanation:
9x+53>= 115
Subtract 53 from both sides
9x+(53-53) >115-53
9x>62
Divide both sides by 9.
9x÷9>62÷9 = 6.889
