Answer:
54
Step-by-step explanation:
its a sequence. they are multiplying by 3 each time.
Answer:
x = 11
Step-by-step explanation:
These angles are alternate exterior angles which means they are equal to each other:
5x + 9 = 6x - 2
5x - 6x = -2 - 9
-x = -11
x = 11
Answer:
15 sides
Step-by-step explanation:
Always the sum of interior angle and exterior angle = 180
Let the exterior angle = x
Interior angle = 6.5 *x = 6.5x
x + 6.5x = 180
7.5x = 180
x = 180/7.5
x = 24
Exterior angle = 24°
Sum of exterior angles of any polygon = 360
number of side = Sum of exterior angles ÷ measure of each exterior angle
= 360 ÷ 24
= 15
