Given:

Four lines are marked proportion, the length of TW can be determined by

Value of a:

Let us set the proportion for the given lines.

Thus, we have;

Thus, the value of a is 5.6

Value of b:

Let us set the proportion for the given lines.

Thus, we have;

Thus, the value of b is 5.

Length of TW:

The length of TW is given by

Thus, the length of TW is 13.6

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

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
