Answer:

Step-by-step explanation:

note that sin x = cos(90 - x ) ← Cofunction identity

Solve this equation. -4(p+2)+8=2(p-1)-7p+15

ratelena [41]

Hey there!

First we have to $distribute$ !

$-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\ -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15$

Now, we have to $combine$ our like terms

$-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15 
$

Once we solve all the $like-terms$ we get

$-4p = 5p +13$

Now, we have to $add$ $5p$ to each of your sides

$-4p + 5p \\ = -5p + 13 + 5p$

Solve that part of the equation

$p= 13$

Good luck on your assignment and enjoy your assignment

How many sides does a regular polygon have if the measure of one of it's interior angles is 144?

butalik [34]

Each Interior Angle = 180° - (360 / sides)
144 = 180 - (360 / sides)
(360 / sides) = 36
sides = 360 / 36
sides = 10
It is a decagon.

It could be 5000 and 2, because 2 is a single digit and the product equals 10000.
