Answer:
x=1
Step-by-step explanation:
3/4x + 1/4 =2x
3/4x=2x-1/4
3/4x-2x= -1/4
3/4x-8/4x= -1/4
-5/4x= -1/4
x= -1/4+ 5/4
x=4/4
x=1

Step-by-step explanation:
It is common knowledge that the sum of the angles in a triangle is 180° but how about in polygons with a greater numbers of angles? If we are given a convex polygon with n sides and S is the sum of the measures of the interior angles then S = 180(n - 2).
Ex.
Find the sum of the measures of the interior angles in an octagon.
The octagon has 8 sides and we plug this value into our formula:
S = 180(8 - 2) = 1080°
Hence the sum of the measures of the interior angles in an octagon is 1080°.
Another thing with convex polygons is that the sum of the measures of the exterior angles is always 360°
m∠A+m∠B+m∠C+m∠D+m∠E+m∠F=360
