36.25 = 8.75*x
36.25/8.75 = x
x = 4.1428571429 feet in length
Answer:
6 sides
Step-by-step explanation:
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Let us represent:
Sum of Exterior angle as x
Sum of Interior angle as y
Note that:
The sum of the exterior angles of a polygon = 180 - The sum of the interior angles
Hence,
The sum of the exterior angles of a polygon + The sum of the interior angles = 180
x + y = 180
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles.
2x = y
Substituting
x + 2x = 180°
3x = 180°
x = 180/3
x = 60°
Solving for y
2x = y
2 × 60° = y
120° = y
Hence,
Sum of Exterior angle as x = 60°
Sum of Interior angle as y = 120°
The number of sides of a polygon is
360°÷ Sum of Exterior angles
= 360° ÷ 60
= 6 sides
Answer:
Step-by-step explanation:
If angle 5 = 4x + 15, and angle 4 = 6x - 5, and angle 5 = angle 4, then:
4x + 15 = 6x - 5 and
20 = 2x so
x = 10. Now sub this back in for x in angle 5's expression:
angle 5 = 4(10) + 15 ---> 40 + 15 ---> angle 5 = angle 4 = 55 degrees
Answer:
yes
Step-by-step explanation:
34.95 + 15.75(4)
34.95 + 63 = 97.95
First you subtract the $8 from the $20 so you have $12 that you bough 6 highlighters with. Then you do the math and each highlighter cost $2
