Answer:
x = 6 ±
Step-by-step explanation:
To find the zeros equate f(x) to zero , that is
2(x - 6)² - 4 = 0 ( add 4 to both sides )
2(x - 6)² = 4 ( divide both sides by 2 )
(x - 6)² = 2 ( take square root of both sides )
x - 6 = ± ( add 6 to both sides )
x = 6 ±
The zeros are x = 6 - , x = 6 +
Step-by-step explanation:
∠AOC is right angle = 90°
∠AOB = 53°
∠BOC = x°
x = ∠AOC - ∠AOB
= 90° - 53°
= 37°
So, the value of x is 37°
