Answer:
Step-by-step explanation:
Since cotangent of angle is:
And
- cos λ = x/1, sin λ = y / 1
The value of cot λ is:
- cot λ = x/y = - 0.358/0.934 = - 0.383 (rounded)
Correct choice is B

Let's solve ~
First we have to calculate g (-5) :



Now, let's find f (g (-5)) :





Answer: -6.25
Step-by-step explanation: 0.5 -3(0.5+1)^2
=0.5 -3(1.5)^2
= 0.5 -3(2.25)
= 0.5-6.75
= -6.25
Area of a Triangle: 1/2 bh
Therefore: 1/2 6.8 (4.3)
Answer: 3.4 x 4.3 = 14.62
