Step-by-step explanation:
0.75 yard = 1 costume
1 yard = 1/0.75 =4/3 costume
6 yards = 4/3 × 6 = 8 costumes
if you wanna check,
8 costumes = 6 yards
1 costume = 6/ 8
= 3/4 (0.75) yard
The answer is c, since they both add up to 90°
Answer:
8 sides
Step-by-step explanation:
let x be the exterior angle then 3x is the interior angle
interior angle + exterior angle = 180° , then
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
the sum of the exterior angles of a polygon = 360°
since the polygon is regular with each exterior angle = 45°, then
number of sides = 360° ÷ 45° = 8
