Answer:
53.52°
Step-by-step explanation:
The cosine function relates the angle to the sides shown:
Cos = Adjacent/Hypotenuse
cos(x°) = (22 ft)/(37 ft) = 22/37
The inverse cosine function is used to find the corresponding angle.
x° = arccos(22/37) ≈ 53.52°
X = 4×3 X + 7
Resultado
X = 12 X + 7
Forma alternativa
-11 X - 7 = 0
X = -7/11
Ok so factoring quadratics is fairly easy once you get the hang of it
So we have a quadratic
My first question would be what 2 numbers multiply to -2 and add to +1
the answer is 2 and -1
Second question what 2 values multiply to get
the answer x and x
your factored form would be
This is as far as i can explain there is a whole lot about quadratics to be learned. You have to ask your teacher on more information
