88 degrees is the answer. You would start by setting up the equation as (5x+7)+(8x+8)+(3x+5)=180 because all angles of a triangle have a sum of 180 degrees. From there you combine like terms which would leave the answer of being 16x+20=180 then you subtract the 20 from 180 to get x by itself. Then that would leave you with 16x=160 then you divide both sides by 16 to get x=10. From there you plug 16 into the x in the planetarium equation which is 8(10)+8 which equals 88 degrees

Answer:
see below
Step-by-step explanation:
CD = 90 - 53 = 37°
AB = 180 - 79 - 53 = 48°
ED = 180 - 37 = 143°
EB = 180 - 53= 127°
BDE = 53 + 37 + 143 = 233°
DEC = 360 - 37 = 323°°

Answer:
<h2>Factor perfect squares out of the square root until there are no more perfect squares inside.</h2>
Step-by-step explanation:
<h2>Begin by working inside the square root itself. You can manipulate the interior of the square root as much as you'd like so long as you don't violate any other rules of algebra. </h2>
<h2>√160=√16⋅10</h2>
<h2>Because 16 is a perfect square, we can pull it out of the square root as a 4.</h2>
<h2>That will simplify down to 4√10</h2>
<h2>because there are no additional perfect square factors in 10, the resultant is simplified.</h2>
<h2>Therefore, √160 simplifies to 4√10</h2>
