The function ff is defined by f(x)=x^2+4x-2\sin\left(x\right).f(x )=x 2
+4x−2sin(x). Use a calculator to write the equation of the line tangent to the graph of ff when x=1.x=1. You should round all decimals to 3 places.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

step-by-step explanation:

your mom

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

b. f(x) = –√x + 3this is the correct answer
