Hello from MrBillDoesMath!
Answer:
3/tan(35) (approximately 4.3)
Discussion:
From plane trigonometry
tan (35) = (side opposite angle )/(side adjacent angle)
= 3 / ? (*)
Multiply both sides of (*) by ? to get
? tan(35) = 3/? * ? = 3
Divide both sides by tan(35) to get
? = 3/tan(35)
= 3 /(.700 ) approximately
= 4.3
Thank you,
MrB
