Evil Kanevil is getting ready to perform a death defying stunt for a large crowd of people. He plans to jump over a row of cars from a ramp that from base to base is 8 feet long and is tilted at a 40 degree angle. Evil needs to be at least 7 feet in the air to clear the cars, otherwise he'll crash and his stunt career will be over. Find out if the technicians built the ramp high enough for Evil.​

answer is because 4×10=40

and 98×4= is 392

40,392

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
