Question

Find the missing side of triangle

Answer 1

x = 20

Explanation:

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

formula:
`a=√(c^2-b^2)`

a = x

b = 21

c = 29

a =
`√(29^2-21^2)`

a =
`√(841-441)` (note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)

a =
`√(400)`

a = 20

x = 20
