<span>ABCD is an isosceles trapezoid with legs AB and CD
∴ AB = CD
</span>
<span>AB = 6y +5
</span>
<span>CD= 2y +1
∴ 6y + 5 = 2y + 1
6y - 2y = 5 - 1
4y = 4
∴ y = 4/4 = 1

Answer:
Step-by-step explanation:
We are given two fractions and are asked to simplify it.
So
We can follow the exponent rule of subtracting them since both fractions are the same value.
Now do the negative exponent rule :
Move the negative in between the fraction :
And apply the fraction switcharoo :
The proof of the equation (sin²x) / (1-cosx) = (secx+1) / (secx) is given below.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The equation is given below.
(sin²x) / (1-cosx) = (secx+1) / (secx)
Taking the left-hand side, then we have
⇒ [sin²x / (1 - cos x)] × [(1 + cos x) / (1 + cos x)]
⇒ [sin²x (1 + cos x)] / [1 - cos² x)]
⇒ [sin²x (1 + cos x)] / [sin² x)]
⇒ 1 + cos x
⇒ 1 + 1/sec x
⇒ (sec x + 1) / sec x = Right-hand side
