Find the ratio of the area of triangle xby to the area of triangle abc for the given measurements, if

by = 2, bc = 4

1/3
1/4
1/2

B. 1/4

Step-by-step explanation:BY/BC=2/4=1/2

Area ratio:

Area of triangle XBY / Area of triangle ABC = (BY/BC)²

=(1/2)²

=1/4

So the answer is B.  1/4

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

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
