Question

What is the value of x to the nearest tenth?

A. 10.5
B. 23.5
C. 4.8
D. 14.1

Answer 1

Hello!

You can use the Pythagorean Theorem

18.8 / 2 = 9.4


`4.7^(2) + 9.4^(2) = c^(2)`

square the numbers


`22.09 + 88.36 = c^(2)`

Add


`110.45 = c^(2)`

Take the square root of both sides

10.5 = c

The answer is A) 10.5

Hope this helps!

Answer 2

18.8 / 2 = 9.4

x^2 = 4.7^2 + 9.4^2
x^2 = 22.09 + 88.36
x^2 = 114.45
x = 10.5

answer
A. 10.5
