12 I’m pretty sure because you have x then 3 then 12
Answer:
63/2 or 31.5
Step-by-step explanation:
we can split this shape into 2, a triangle and a rectangle
A triangle = bh/2 = 7*3*1/2 = 21/2
A rectangle = b*h = 3*7 = 21
21/2 + 21 = 63/2
The grasshopper is 5X+2-(2x-1)=3x+3 inches longer than the spider.
The identity Sin(α)/Tan(α) = Cos(α) is valid
Trigonometry is study of triangles. All trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side. Three major of them are as follows :-
Sine Function:
sin(θ) = Opposite / Hypotenuse
Cosine Function:
cos(θ) = Adjacent / Hypotenuse
Tangent Function:
tan(θ) = Opposite / Adjacent
Lets prove this identity by proceeding with the LHS
= Sin(α)/Tan(α)
= Sin(α)/ (Sin(α)/Cos(α)) (Tan(α) = Sin(α)/Cos(α))
= Sin(α)xCos(α) / Sin(α)
= Cos(α)
Hence verified
