For angle one do 180-74 then divide by two and it will give you the angle for angle one and for angle two you just add the angle given and angle one then subtract by 180
This is my answer. How you think about my answer?
<u>4 sec²(x) = 8</u>
Divide each side by 4: sec²(x) = 2
Take the square root of each side: sec(x) = + or - √2
We know that sec(x) = 1/cos(x)
So the equation becomes 1/cos(x) = + or - √2
Divide '1' by each side: cos(x) = + or - (1/2) √2
x = <em>45°, 135°, 225°, 315°
</em>
Here it is...................
A) is the answer. The island in decaying by 10% each year, which means the amount will change within the period of the decay.
