Question

Two sides of a triangle are 16.2 cm and 29.6 cm, with the included angle 106◦. What is the length of the third side?

Answer 1

37.45593...cm

Explanation:

`a^2=b^2+c^2-2bcxxcosA`

`a`= length you are finding
`b`= 16.2cm
`c`= 29.6cm
`A`= 106

`a^2=16.2^2+29.6^2-2xx16.2xx29.2xxcos(106)`
`a^2=1402.94725`
`a=sqrt140294725=37.45593...`
