A scientist was in a submarine below sea level studying ocean life over the next

199.5 ft

Step-by-step explanation:

Given: A scientist was in a submarine below sea level studying ocean life over the next 10 minutes she went down 58 ft.

If she was 141.5 ft below sea level after she went down , then she had been (141.5 ft + 58 ft) = 199.5 ft below sea level.

Hence, If she was 141.5 ft below sea level after she went down , then she had been 199.5 ft below sea level.

Explanation:

The sine of angle x° is the ratio of y to the sun-moon distance. All the scientist has to do is divide distance y by the sine of the angle x° to find the sun-moon distance.

  sin(x°) = y/(sun-moon distance)

  sun-moon distance = y/sin(x°)
