Answer: Imma go with B
Step-by-step explanation:
Answer: The area of the bottom figure is 5/8 ft²
Step-by-step explanation: The area of a triangle is half of the base times the height. Multiply the dimensions given, then divide by 2 or multiply by 1/2
The base of the top diagram is obscured by the timer.
The bottom will be 3/4 × 5/3
Multiply numerators straight across : 3 × 5 = 15
Multiply denominators straight across : 4 × 3 = 12
15/12 Simplify to 5/4 and take half (multiply by 1/2)
The result is 5/8 square ft.
The given expression is 
We need to determine the expression as an equivalent algebraic expression involving only x.
The expression has to be expressed as an algebraic expression in x.
Thus, we have;
Using the identity 
in the above expression, we get;
Simplifying, we get;
![\cos \left(2 \cos ^{-1} x\right)=2[cos(cos^{-1}x)]^2-1](https://tex.z-dn.net/?f=%5Ccos%20%5Cleft%282%20%5Ccos%20%5E%7B-1%7D%20x%5Cright%29%3D2%5Bcos%28cos%5E%7B-1%7Dx%29%5D%5E2-1)
Hence, the expression can be written as
