Answer:
a) Only the first one is an identity.
Step-by-step explanation:
1). 8 cos O tan O csc O = 8 simplifies to:
cos O tan O csc O = 1
cos O * (sin O / cos O) * (1 /sin O)
= cos O sin O / cos O sin O
= 1
So it is identity.
2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O
= 13 sec^2 O - tan^2 O / cos^2 O
Now sec^2 O = 1 + tan^2 O, so we have:
(13( 1 + tan^2 O) - tan^2 O) / cos^2 O
= (12 tan^2 O + 13) / cos^2 O
This is not always = 2 so its not an identity.
A tangent line to a circle is perpendicular to the radius drawn to the tangent point.
If tangents are constructed through points L and J, then<span> the tangents are perpendicular to the diameter and parallel to each other.</span>
Answer:
12 feet
Step-by-step explanation:
Since the side length is a length, it will be positive and not negative, so we solve this equation for s by taking the positive square root of both sides of the equation. We get that s = 12, so the side length of a square with an area of 144 square feet is 12 feet.While -12 is "a square root" of 144, the square root operation here denotes a function from nonnegative real numbers to nonnegative real numbers. A function can only produce a single result. So the expression √144 evaluates to the positive root 12.Because one square foot is 144 square inches, divide the total number of square inches by 144.
