=> The first expression on the left: (1 + tan²)
we know that tangent = sin/cos
so tan² = sin²/cos²
the expression is <u>(1 + sin²/cos²)</u>
=> The second expression on the left: (1 - sin²)
we know that (sin² + cos²) = 1
subtract sin² from each side,
and we have (1 - sin²) = (<u>cos²)</u>
=> Multiply the massaged form of the two expressions:
(1 + tan²) (1 - sin²) = (<u>1 + sin²/cos²)</u> (<u>cos²)</u> = (cos² + sin²) = <em>1 </em>qed

Answer:
m
Step-by-step explanation:
Given parameters:
Length of rope = 11m
First length cut off =
m
Second length cut off =
m
Unknown:
Remaining length = ?
Solution:
Let us find the total length cut off first;
=
m +
m
= 
=
m
So,
Remaining length = 11 - 
=
=
m
