Answer:

103

Step-by-step explanation:

This shape is pentagon.

Note : -

Sum of interior angles of a pentagon is 540.

115 + 105 + 117 + 100 + x = 540

437 + x = 540

x = 540 - 437

x = 103

In the spring a young maple is 18 feet tall. Over the summer it grows 8%. How
Setler79 [48]

Answer:

At end of summer, the Maple is 19.44 feet

Step-by-step explanation:

We need to find 8% of 18 feet and add it to 18 to get the new height.

To get percentage to decimal, we need to divide by 100. Hence

8/100 = 0.08

8% of 18 is:

18 * 0.08 = 1.44 feet

Now, we need to add this to 18 feet. We have:

18 + 1.44 = 19.44 feet
