Triangle 1: a(6,6), b(12,9), c(9,6)
triangle 2: a′(2,2), b′(4,3), c′(3,2)

how are the lengths of the sides of the two triangles related?

a. triangle 2 has sides that are three times longer than triangle 1.
b. there is no relationship.
c. triangle 2 has sides that are one-third as long as triangle 1.
d. triangle 2 has sides that are half as long as triangle 1.

answer:

is b

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
