Which equation does the graph of the systems of equations solve? A) −one thirdx + 1 = 2x − 4
B) one thirdx + 1 = −2x − 4
C) one thirdx + 1 = 2x − 4
D) −one thirdx − 1 = −2x − 4

the square root of what number? if you add that, then someone will probably answer the question.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

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
