A tree is 18 feet tall and casts a shadow 12 feet long. A building nearby casts a shadow that measures 22 feet long. How tall is the building?

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually
