First your take 55 and divide it by 20 to find out have many feet is equivalent to 1 inch. 2.75 feet is equivalent to 1 inch. then you divide that by 8 to find your 1/8 inch equivalent. 2.75/ 8 is equal to .34 feet per 1/8 inch.
F(x) = 5x - 2
f(-3/5) = 5(-3/5) - 2
f(-3/5) = -15/5 - 2
f(-3/5) = -3 - 2
f(-3/5) = -5
Answer:
60°
Step-by-step explanation:
2x and x are linear pair,
=> 2x + x = 180
=> 3x = 180
=> x = 180/3
=> x = 60°
=>2x =120°
