Pl help m i will give brainlist pls Area of triangle ABC = 12.8 square units
Area of triangle ACD = 18.4 square units
Area of triangle AED = 14.8 square units

A polygon ABCDE is shown. The vertices A and D are joined with a dashed line, and the vertices A and C are joined with a dashed line.

The area of Figure ABCDE is square units. (Input whole number only.)

y=mx+b

step-by-step explanation:

m slope

b y-intercept

where is the gragh

step-by-step explanation:

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
