Answer:

see explanation

Step-by-step explanation:

Consider the left side

1 + cot²A

= 1 + $\frac{cos^2A}{sin^2A}$

= $\frac{sin^2A+cos^2A}{sin^2A}$

= $\frac{1}{sin^2A}$

= cosec²A

= right side, thus proven

Write the slope intercept equation for line AB

strojnjashka [21]

Answer:

Y = 2

Step-by-step explanation:

The answer choices are in slope intercept form which is Y=mx+b. Since the slope is 0, there is no need for "mx" in the equation, so y= 2 where b is 2
