The value of a variable that satisfies a given algebraic equation

The value of the variable in an equation which satisfies the equation is called a Solution to the Equation.

example: So for example we take the equation 2n=10, If n = 1, the number of matchsticks is 2.

c. 4 1/4 pounds

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
