Answer:
dependentt
Step-by-step explanation:
Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
Part A:
Part B: Degree = 2, Classification = Quadratic
Part C: The polynomial is closed because it is multiplied. You CANNOT close under division.
Step-by-step explanation:
(i)
m <em>L</em><em> </em>BOC = 2× m <em>L</em><em> </em>BAC = 2×56 = 112°
(ii)
m <em>L</em><em> </em>BCA = m <em>L</em><em> </em>BAT = 75°
m <em>L</em><em> </em>OCB = (180°-112°)/2 = 68°/2 = 34°
so, m <em>L</em><em> </em>OCA = 75°-34° = 41°
