Answer:

x=55

a=11.47

Step-by-step explanation:

To find x we add all the angles in the triangle.  The three angles in a triangle add to 180 degrees

35+x+90 = 180

Combine like terms

125+x=180

Subtract 125 from each side

125-125+x=180-125

x= 55

To find a

sin 35 = opposite side/ hypotenuse

sin 35 =a/20

Multiply each side by 20

20sin35 =a

11.47152873 =a

Ms. Moneyhun's son, Sam, just learned to crawl. He can crawl 20 ft in one minute. How many feet can Sam crawl in one hour? (Hint
almond37 [142]

Answer:

1200 ft in one hour

Step-by-step explanation:

The ratio of Sam crawling 20 ft in one minute can be written as:

20:1

Multiply the ratio by 60 to get the minutes to 60 minutes, because there are 60 minutes in an hour:

 20    :    1

×60     ×60

To get:

1200:60  ⇒  This means Sam can crawl 1200 ft in 60 minutes, which is the same as 1200 ft in one hour.

<em>Hope this helps!</em> :)
