Answer:
Step-by-step explanation:
You see that there’re angles with 30 and 90 degrees that means that -> 180-(90+30)=60 (measurement of the third angle)
Here you’ll need to use the 30,60,90 degree triangle rule:
The opposite side of 30 degree will be y
30->y
90->2y->12√3 => y=6√3
60->y√3->x => 6√3x√3=6x3=18
To understand the rule better you can check the picture below.Wish it will help you!Good luck!
Answer:
B. 2340
Step-by-step explanation:
Interior angles of a polygon is given by
(n – 2)180 where n is the number of sides
(15-2) *180
13*180
2340
Answer: your answer would be
x-30y=100 and 10y = x - 20
Step-by-step explanation:
The question ask to determine what is a regular polygon that contains an interior angle of 9000 degree, base on my research, according to the geometrical research, I would say that the said polygon is a 52 sided convex polygon. I hope this would help
Answer:
it is a because you subtract the ten from both side and that makes the -8 into a -18 then you divide by 3 and your answer is -6
