<h2>Answer:</h2>

The slope will be 0.09

<h2>Step-by-step explanation:</h2>

The slope of a surface is seen when one end or side is at a higher level than another or a rising or falling surface.

Slope of a surface is given by

Slope = rise / run

In the given case rise is 4.5 feet and the run is 50 feet

Slope = 4.5 / 50

Slope = 0,09

Vera_Pavlovna [14]

Find missing length :

a² + b² = c²
c² = 19² + 34²
c² = 1517
c = √1517
c = 38.95 units.

Find missing angle A:

$\dfrac{a}{\sin(a)} = \dfrac{c}{\sin(c)}$

$\dfrac{19}{\sin(a)} = \dfrac{38.95}{\sin(90)}$

$\sin(a) = 0.488$

$a = sin^{-1} (0.488)$

$a = 29.2 \textdegree$

Find Missing B:

$\dfrac{b}{\sin(b)} = \dfrac{c}{\sin(c)}$

$\dfrac{34}{\sin(b)} = \dfrac{38.95}{\sin(90)}$

$\sin(b) = 0.873$

$b = sin^{-1}(0.873)$

$b = 60.8 \textdegree$

Answer: Missing length = 38.95 units ; Missing angles = 29.2° and 60.8°
