Answer:
12.0 cm
Step-by-step explanation:
The Pythagorean theorem applies:
(12 cm)² +b² = (17 cm)²
b² = (289 -144) cm² = 145 cm²
b = √145 cm ≈ 12.04 cm
b ≈ 12.0 cm . . . . rounded to 1 decimal place
Answer: 60 inches
Step-by-step explanation:
Let x be the height of son in the beginning of the year.
If the height is increased 110% at the end of the year , then his height in the end of the year = 110% of x
[since 110%=1.1]
Since, his height at the end of the year = 66 inches
![\\\Rightarrow\ 1.1 x=66\\\Rightarrow\ x=\frac{66}{1.1}=60](https://tex.z-dn.net/?f=%5C%5C%5CRightarrow%5C%201.1%20x%3D66%5C%5C%5CRightarrow%5C%20x%3D%5Cfrac%7B66%7D%7B1.1%7D%3D60)
Hence, the height of Mrs. Peters son in the beginning of the year is 60 inches.
