Step-by-step explanation:
Answer:
The correct option is A.
Step-by-step explanation:
The correct form is:
4sin^2 x − 1 = 0
First step is add 1 to both sides:
4sin^2 x-1+1=0+1
4sin^2 x=1
Now to eliminate 4 divide both sides by 4
4sin^2 x/4=1/4
sin^2 x=1/4
Take square root at both sides
√sin^2 x = √1/4
sinx = 1/2
Thus the correct option is 30° ....
Step-by-step explanation:
do you have a calculator that could count these? with it it would be easy.
anyway here are the first ones and thanks for the one star
Length of the rectangle is 5 inches
Step-by-step explanation:
- Step 1: Perimeter of the rectangle = 26 in and width = 8 in. Find the length.
Perimeter of the rectangle = 2(length + width)
26 = 2(length + 8)
13 = length + 8
length = 13 - 8
Length = 5 in
