Answer:
I think the answer to the equation is 4.
Answer:
A
Step-by-step explanation:
- f=1/2(a+b)×h
- 1/2(1.6+4)×2
- 2.8×2
- 5.6 since to round off 5.6 to the nearest tenth consider the hundredths' value of 5.6 which is 0. therefore the tenths value of 5.6 remains 5.6

Answer:
tan θ = -√7/3
Step-by-step explanation:
We have the equation as following:
=> (cos x)^ 2 = 1 - (sin x)^2
So that:
(cos θ)^2 = 1 - (sin θ)^2 = 1- (√7/4)^2 = 1 - 7/16 = 9/16
=> (cos θ)^2 = 9/16
<em />
We have the equation:
=> (tan θ)^2 = 1/(cos θ)^ 2 - 1 = 1/(9/16 ) - 1 = 16/9 - 1 = 7/9
<em>=> tan θ = √7/3 or tan θ = -√7/3 </em>
<em />
As θ is in the quadrant II, so that tan θ would have the negative value
=> tan θ = -√7/3
Answer C is correct
