Answer:
12
Step-by-step explanation:
since tile B is a regular polygon means it is an equilateral triangle. The angle inside B would be 60.
(360 - 60)/2 = 150 (interior angle of tile A)
180 - 150 = 30 (exterior angle of tile A)
therefore number of sides = 360 /30 = 12
Answer:
24,150
Step-by-step explanation:
Given that :
Salary earned this year = 23,000
Percentage Raise in salary for the new year = 5%
The new yearly salary can be obtained thus ;
(100% + percentage raise in salary) * salary earned this year
(100% + 5%) * 23,000
105% * 23000
1.05 * 23000
24,150
-10 and 2
-10 x 2 = -20
-10 + 2 = -8
Answer:
-1
Step-by-step explanation:
The formula to find the slope of a line is:

where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:

This means the slope of the line is -1.
