Answer:
6 sides
Step-by-step explanation:
the interior angle + the exterior angle = 180°
let x be the exterior angle then 2x is the interior angle and
x + 2x = 180
3x = 180 ( divide both sides by 3 )
x = 60
the exterior angle = 60°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular the the exterior angles are congruent, then
number of sides = 360° ÷ 60° = 6
3x -4 (5 - x) = 7x -20
3x-20+4x=7x-20
7x-20=7x-20
Answer:
120
Step-by-step explanation:
Find out the answer for 78^ - 42^.
78^ - 42^ = 4320
36 x = 4320
1 x = 4320 ÷ 36 = 120
$67.87 rounded to the nearest 10 dollars is $70. 25% of $70 is $17.50.
