Answer:
f(86)-f(82)
Step-by-step explanation:
well f of 82 = 2 plus _ plus _ plus _ and f of 86 is 2+_+_+_ subtract them
(A) 3 (B) 4 (C) 47 (D) 59 (E) 83
these are some possible answers so the answer is b, 4
btw, 86-82 = 4 duh
What is angle A’s equation
In the figure below
1) Using the theorem of similar triangles (ΔBXY and ΔBAC),
Where
Thus,
thus, BC = 7.5
2) BX = 9, BA = 15, BY = 15, YC = y
In the above diagram,
Thus, from the theorem of similar triangles,
solving for y, we have
thus, YC = 10.
If u were to add 5x+20=9x you’d get x=5
