Step-by-step explanation:
-This is an addition/subtraction problem.
#We subtract the sum of the first two expression from the third expression:
Hence, the expression must be added to the first two.
2 + x = -19 <=> x = -19 -2 = -21
Y o = 2 sin ( π/6 ) = 2 * 1/2 = 1
x o = π / 6
y ` = 2 cos x = 2 cos (π/6) = 2 * √3 / 2 = √ 3;
m = √3
An equation of the tangent line is:
y - y o = m ( x - x o )
Answer:
y - 1 = √3 ( x - π/6 )
Answer:
∠BCD = 34°
Step-by-step explanation:
∠FCE + ∠FCA + ∠ACB = 180° ( straight angle ), thus
∠FCE + 90 + 56 = 180, that is
∠FCE + 146 = 180 ( subtract 146 from both sides )
∠FCE = 34°, hence
∠BCD = ∠FCE = 34° ( vertical angles )
