Answer:
x = 5.2
Step-by-step explanation:
Measure of interior angle of a regular polygon = 
Here n = number of sides of the polygon
Interior angle of a regular pentagon = 
= 108°
By applying cosine rule in ΔABK,
(BK)² = (AK)² + (AB)² - 2(AK)(AB)cos(108)°
(x + 3)² = 4² + 6² - 2(4)(6)cos(108)°
x² + 6x + 9 = 16 + 36 - (-14.83)
x² + 6x = 57.83
x² + 6x - 57.83 = 0
x = 
x = 
x ≈ -11.2, 5.2
Since, x can't be negative,
x = 5.2 will be the answer.
Answer:
c. 2/3
Step-by-step explanation:
Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.
The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.
Answer: Could we see the circle we need to find the circumference for?
Step-by-step explanation:
Answer:
1=101 4=79 2=79
Step-by-step explanation:
Angle 3 is given as 101. The angle across from it has to be the same angle measure so angle 1 is 101. Because the angle 4 added to 3 is a straight line or 180 degrees (half a circle) than you just have to subtract angle 3 from 180 to get angle 4 which is 79. Angle 4 and angle 2 have to be the same so angle 2 is 79. I hope this helps
