Answer:
Step-by-step explanation:
hello :
sin x + 2 sin x cosx = 0 equivalent to : sinx(1+2cosx) =0
sinx=0 means : general solution is : x= kπ....k in Z
1+2cosx=0 means : cosx= -1/2 general solution is : x= ±π/6+kπ...k in Z
Answer: I and II.
Step-by-step explanation:
By definition, two solids are similar if their corresponding sides are in the same ratio.
Knowing this, let's find which solids are similar:
Corresponding sides ratio of solids I and II:
Corresponding sides ratio of solids I and III:
Corresponding sides ratio of solids II and III:
You can observe that the solids I and II are similar.

Answer:
Step-by-step explanation:
1.
Formula for Area of a parallelogram: A = bh
So multiply the base (25cm) by the height (16cm) to get 400cm^2.
2.
Volume formula l x w x h
Multiply the length of the pool (20ft) by the width (15ft) by the height (6ft) to get 1,800ft^2
3.
Formula for Area of a trapezoid A= a+b/2 * h
Where a is (12.6in), b is (15in), and h is (3.4in) just plug in the numbers into the formula to get 46.92in^2
4.
Same thing as number one, use the Area of a parallelogram formula A = bh
