.

As a result, .

Try the same steps for the triangle in b. .

Question c includes a rectangle. The lengths of opposite sides of a rectangle are equal. As a result, for the right triangle with a right angle at the lower-right corner of the rectangle:

Apply the Pythagorean Theorem:

As a result,

y = x + 95

y = 42 + 95

y=137 mm hg

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
