The answer is 20 since 1/5 of 20 is 4, and 20 + 4 = 24.
Answer:
there both cercles
Step-by-step explanation:
Step-by-step explanation:
It is given that the angels of a triangle have a sum of 180°. The angles of a rectangle have a sum of 360°. The angels of a pentagon have a sum of 540.
<u>Let me define the each terms.</u>
1. We know that each angle in a triangle is 60°, So there is a three angle in a regular triangle.
2. We know that each angle in a rectangle, is 90°, So there is a four angle in a regular rectangle.
Similarly,
- There is 8 angle in a regular octagon and each angle measurement is 135°.
So, sum of the angles of an octagon = 135° × 8
Sum of the angles of an octagon = 1080°
Therefore, the required sum of the angles of an octagon is 1080°
m = -1
Step-by-step explanation:
-16m = 7 + 9
-16m = 16
m = 16 ÷ -16
m = -1
Each term differs by -68 and the first term is -68, we have:
As an expession it's just -68n.
