Answer:

(a)55^o

(b)350.1ft

Step-by-step explanation:

The sum of the angles inside a triangle must be 180°, but from the right angle we already have 90°, so the sum of the two acute angles is 90°, then:

90^o-35^o=55^o

Let s be the length of the shadow and h the height of the three, so tan(35) is

tan(35^o)=\frac{h}{s}

Solving that last equation for h:

h=s*tan(35)=500(0.7002)=350.1ft
