Answer:

7y8.9 ft²

Step-by-step explanation:

Easy way:

Rotate the triangle so that the 12.1 ft side in on the bottom becomes the base.

Drop a line from the top down perpendicular to the 12.1 ft base. That makes a right triangle.

sin 71 = height/13.8

0.9455 = height/13.8

height = 13.05 ft

Area = bh/2 = (12.1)(13.05)(0.5) = 78.9 ft²

Bob can ride his bike 6.5 miles in 20 minutes what is the rate of speed in miles per hour
vladimir2022 [97]

Answer:

19.5 miles per hour

Step-by-step explanation:

We need to change 20 minutes to hours

1 hours = 60 minutes

20 minutes * 1 hour/60 minutes = 1/3 hour

To find miles per hour we take the miles and divide by hours

6.5 miles

---------------- = 19.5 miles per hour

1/3 hours

56+34=n+30? Do you add 56+34 =90-30=60 n=60?
slamgirl [31]

You're on the right track. Start by combining like terms on the left side of the equation by adding 56 and 34.

90 = n + 30, now subtract 30 from both sides of the equation to isolate the variable n.

60 = n is the answer.
