Answer 2

Calculating the Height of Zhenya

To find the height of Zhenya, we can use the information provided about the difference between his jump result and his height, as well as the difference between his jump result and his sister's height.

Let's denote: - Zhenya's height as Z - Zhenya's jump result as J - Zhenya's sister's height as S

We are given the following information: 1. The result of Zhenya's jump is 34 cm less than his height: J = Z - 34 2. The result of Zhenya's jump is 10 cm more than his sister's height: J = S + 10 3. Zhenya's sister's height is 1 m 5 cm, which is equivalent to 105 cm: S = 105

Using these equations, we can solve for Z, the height of Zhenya.

First, we can substitute the value of S into the second equation: J = 105 + 10

Now, we can substitute the value of J from the first equation into the equation above: Z - 34 = 115

Solving for Z: Z = 115 + 34

Z = 149

Therefore, the height of Zhenya is 149 cm.
