Answer:

theta = 9/19 radians or  approximately .4737 radians

Step-by-step explanation:

The formula for arc length is

S = r theta  

where theta is in radians.  Lets put in what we know.  The radius would be 1.9 since the ropes would be the radius.

.9 = 1.9 theta

Divide by 1.9 on each side.

.9/1.9 = theta

theta = 9/19 radians

or in decimal form it is approximately  .4737 radians

kherson [118]

Answer:

10°C

Step-by-step explanation:

The temperature is 50°F

Let's assume that 50°F = x°C

The formula is;

(x°C × \frac{9}{5}) + 32 = 50°F

\frac{9}{5}x°C = 50 - 32 = 18

\frac{9}{5}x°C = 18

x°C = \frac{5}{9} × 18 = 10°C

So 50°F is equal to 10°C.
