Given the following :

Original Price of tennis racket = p

Find the missing side of triangle
Maksim231197 [3]

<u>Final Answer:</u>

x = 20

<u>Step-by-step explanation:</u>

we'll be using the pythagorean theorem method, in this triangle the missing letter is a.

formula: a=\sqrt{c^2-b^2}

a = x

b = 21

c = 29

a = \sqrt{29^2-21^2}

a = \sqrt{841-441}     (note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)

a = \sqrt{400}

a = 20

x = 20
