Solve the following system by graphing. x + y - 6 = 0 x - y = 0 what is the solution of the system?

a. (-3, 3)

b. (3, -3)

c. (3, 3)

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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
