Answer:

Mikhail is 50 years old.

Step-by-step explanation:

Let m represent how old Mikhail is.

110 = (m + 10) + m

Combine equal variables.

110 = 2m + 10

Get the variable alone by cancelling out the 10.

110 - 10 = 2m

Simplify.

100 = 2m

Divide.

m = 50

Dimas [21]

Answer:

119 or 118.726577

Step-by-step explanation:

We should use the Pythagorean Theorem to solve this problem.

a^2+ b^2=c^2

64^2+100^2=c^2

4096+10000=14096

c^2=14096

c=\sqrt{14096}14096

And the root of 14096 is 118.726577.

So the Answer is About 119 meters, or 118.726577

hope this helps!
