Question

15. Solve for x in the diagram.
Х
9
12
A. 15
B. 25
C. 14
O D. 37

Answer 1

Answer:

A. 15

Step-by-step explanation:

Use Pythagorean theorem.

a²+b²=c²

Where the sum of both legs squared equals to the hypotenuse squared.

9²+12²=x²

81+144=x²

225=x²

√225=x

x=15

The value of x is 15.

Answer 2

Answer:

15

Solution,

Hypotenuse(h)=X

Perpendicular (p)=9

Base(b)=12

Now,

Using Pythagoras theorem,

${h}^{2} = {p}^{2} + {b}^{2} \\ or \: {x}^{2} = {(9)}^{2} + {(12)}^{2} \\ or \: {x}^{2} = 81 + 144 \\ or \: {x}^{2} = 225 \\ or \: x = \sqrt{225} \\ or \: x = \sqrt{ {(15)}^{2} } \\ x = 15$

hope this helps...

Good luck on your assignment...
