Use tan theta = \(\cfrac{opposite}{adjacent}\)
So, \(\tan 49 = \cfrac{x}{55}\)

Use your calculator for that.
OpenStudy (gabylovesyou):
1.15
OpenStudy (anonymous):
yes
OpenStudy (gabylovesyou):
yay xD
mathslover (mathslover):
Fine. So,
1.15 = \(\cfrac{x}{55}\)
Multiply 55 both sides :
\(1.15 \times 55 = \cfrac{x}{55} \times 55\)
\(1.15 \times 55 = \cfrac{x}{\cancel{55}} \times \cancel{55}\)
