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°

Answer:

slope is -7/8

Step-by-step explanation:

first remember these to formulas:

$m= \frac{y2-y1}{x2-x1}$

and

$y-y1 = m(x-x1)$

now insert the points:

$\frac{-3-4}{3-(-5)}$ = -7/8

slope intercept form:

y - 4 = -7/8(x - (-5)

y - 4 = -7/8(x + 5)

y = -7x/8 - 3/8

Have a nice day!
