Answer:

$\frac{1}{3x+52}$

Step-by-step explanation:

Given

$\frac{\frac{1}{x^2+51x+50} }{\frac{2}{x+50}+\frac{1}{x+1} }$

= $\frac{\frac{1}{(x+50)(x+1)} }{\frac{2(x+1)+x+50}{(x+50)(x+1)} }$

= $\frac{1}{(x+50)(x+1)}$ × $\frac{(x+50)(x+1)}{2x+2+x+50}$ ← cancel (x + 50)(x + 1) on numerator/denominator

= $\frac{1}{3x+52}$

Answer:

41.8°

Step-by-step explanation:

We solve using the Trigonometric function of Sine

Hypotenuse = 15cm

x = θ

Opposite = 10cm

sin θ = Opposite/Hypotenuse

sin θ = 10/15

θ = arc sin ( 10/15)

θ = 41.810314896°

θ = Approximately to 1 decimal place = 41.8°

Therefore, x = θ = 41.8°
