Question

1. Find the value of x to the nearest tenth A. 19.2 B. 20.8 C. 21.3 D. 19.7

Answer 1

Answer:

20.8

Step-by-step explanation:

Use the Pythagoras's Theorem

12²-36²=$\frac{x}{2}$²

144-36=$\frac{x}{2}$²

108=$\frac{x}{2}$²

Root both sides

√108=√$\frac{x}{2}$²

$\frac{x}{2}$≈10.4

$\frac{x}{2}$·2=10.4·2

x=20.8
