Answer:
x + y = 112.5°
Step-by-step explanation:
Step 1 : To find x:
Number of sides in a given regular polygon, n = 8
Each of the angles around a point is xº because given is a regular polygon.
Sum of all the angles of around a point is 360°.
⇒ 8x = 360°
Step 2: To find y:
One interior angle of a regular polygon =
In the given figure, each interior angle is divided by a bisector.
Step 3: Add x+ y
x + y = 112.5°
Answer:
A) P = 6n + 8
Step-by-step explanation:
Given:
Perimeter of the 1 triangle = 24
Perimeter of the 2 triangle = 30
Perimeter of the 3 triangle = 36
Let's check with option A.
P = 6n + 18, where "n" is the number in the figure.
Plug in n = 1, we get
P = 6(1) + 18
= 6 +18
P = 25 True.
Plug in n =2, we get
P = 6(2) + 18
= 12 +18
P = 30 True.
Plug in n =3, we get
P = 6(3) + 18
P = 18 + 18
P = 36, true.
Therefore, the answer is A. P = 6n + 18
Thank you.
