Answer:
A
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= 3x - 2 + x² + 1 ← collect like terms
= x² + 3x - 1
Answer: x= 19
Step-by-step explanation:
Answer:
Option A
Step-by-step explanation:
To find all missing sides of a right triangle we use the sine, cosine or tangent ratio as below,
sinθ = 
cosθ = 
tanθ = 
Now we take an angle measuring 60°
sin(60°) = 

y = 4√3
tan(60°) = 
√3 = 
x = 2√3
Therefore, Option A will be the correct option.
