LHS: cos^2 A( 1+cot^2A)
=cos^2A(cosec^2A) ,1+cot^2A=cosec^2A
=cos^2A( 1/sin^2A)
=(cos^2A/ sin^2A)
=cot^2A
=RHS
Hope this can help.

Don't worry I won't scam you
Step-by-step explanation:
If you look closely at the figure you can see it is divided into fourths, as squares.
We know that squares have a right angle measuring 90°.
We can also see that that 90° is split in two.
So let's do the math...
90° / 2 = 45°
Okay so the giant triangle holding w° has it's corner measuring 45°. So the little parallelogram in the triangle has one of it's angles measuring 45°. Since angles are congruent we know that another angle measures 45°. We also know that a parallelograms angles must always add up to the magic number of 360°. So our equation is
45° + 45° + w° + w° = 360°
90° + 2w° = 360°
90° - 90° + 2w° = 360° - 90°
2w° = 270°
2w° / 2 = 270° / 2
w° = 135°
Hope this helped you. It's really hard to explain through typing without being able to point at the model you gave

Step-by-step explanation:
the percent increase is
(50-20/20)*100=(30/20)*100=150
150% increase
Answer:
The second graph, B, is the correct answer.
Step-by-step explanation:
The answer is B. The coordinate plane at the top has a y-intercept of 10, just like graph B does.
