Answer:
x = 8
I dunno what the question is in the first place, but I assume you are solving for x.
Step-by-step explanation:
The two given angles are equivalent because they are parallel and they have a line that intersects.
The line creates two angles on each side of each line, which is 120 or 60 because there are 180 degs on a straight line.
The obtuse side is 120, and the -8 + 16x is also on an obtuse angle, showing that they are equal.
120 = -8 + 16x
128 = 16x
8 = x
x = 8
1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1
Answer:
-59 feet per minute
Step-by-step explanation:
-539/9 = -59
The formula to find the interior angles is :
(n-2)×180°
Wheras n=the number of sides.
Angles sum of 25-gon therefore will be:
(25-2)×180°
=4140°
Thus,4140° is the answer.
Hope it helps!
