SO first you want to change it to Y=mX+b by getting the y by itself. Subtract 3x over and have -6y=-3x=12 divide both sides by -6 and have y=1/2x-2. To get the perpendicular slope you flip it 1/2 to 2 then change its sign 2 to -2
The new slope is -2
Hi there!

cosec 20 -cot 40= 1/sin 20 - cos 40/sin 40
= (sin 40 -cos 40 sin20)/(sin 40 sin 20)
= 1/sin 40 ( 2 cos 20 - cos 40)
=1/sin20 ( 2 cos(60-40)-cos 40)
=1/sin40( 2 cos 60 cos 40 - 2 sin 60 -sin 40-cos 40)
Put the value of cos 60
= 1/sin 40 ( 2 sin 60 sin 40)
=root(3)
Hope this helped you!
You would divide 44 by 16 so the wing span is 2.75 ft.
The square blanket has 4 sides and all sides are equal.
Length of East side of the blanket = 72 inches
The ribbon will cover all the four equal side.
Then the length of ribbon needed by Risa to cover all sides of the blanket = (72*4) inches
= 288 inches.
Answer:
65
Step-by-step explanation:
They are vertical angles; so angles are congruent
*<em>Vertical angles are always congruent*</em>
<em>Congruent means equal or same.</em>
1) Since they are congruent, you form an equation.
<h2>
145 = 2x + 15</h2>
2) Solve by subtracting 15 from both sides.
<h2>
145 = 2x + 15</h2><h2>
- 15 -15</h2><h2>
----------------------</h2><h2>
130 = 2x</h2>
3) Solve by dividing 2 from both sides
<h2>
130/2 = 2x/2</h2>
4) Simplify
x = 65
