I need the answer .

12.5 feet

Step-by-step explanation:

how to:

lets find the angle that corresponds with the 10 foot side.

to do that we add 50 degrees plus 90 degrees (right angle) to get 140 degrees.

as we know, a triangles angles will total 180 degrees, so 180 - 140 = 40 degrees for the angle corresponding to the 10 foot side.

put these into ratios:

Angle A    =    Angle B

side a              side b

now plug in our numbers:

50 degrees     =     40 degrees

        X                       10 feet

Cross multiply:

50 (10 feet) = 40 (x)

solve for x:

500 = 40 (x)

500/40 = x

12.5 = x

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
