Question

Micheal needs to install a support beam to hold up his new birdhouse, as modeled below. The base of the birdhouse is 25.5 inches long. The support beam will form an angle of 39 with the vertical post. Determine and state the approximate length of the support beam, x, to the nearest inch.

Answer 1

Hi Niya,

I thought I had answered this already.

you should use sin=opp/hypotenuse trigonometric relationship

sin 39= 25.5/ hypotenuse

using this, you can find hypotenuse which is the length of the support beam.

Imp tip: make sure to set your calculator to degrees mode!

hope this helps
