Given parameters:
Each interior angle = 150°
Unknown:
The number of sides of this regular polygon = ?
Solution:
To find the sum of internal angles of a regular polygon, we use the expression below;
(n - 2) x 180 = sum of internal angles of a polygon
n is the number of sides,
Also, the sum of the internal angles of a polygon = number of sides x internal angles;
So;
(n-2) x 180 = 150 x n
Solve for n;
180n - 360 = 150n
180n - 150n = 360
30n = 360
n = 12;
Therefore, the number of sides is 12
I think it's Ecuador. Is it short answer or multiple choice?
A triangle is equal to 180 degrees. we know that one of the angles is 118 and the other is 30 degrees. now we have a total of 148 degrees. so that means the other angle is 32 degrees. and both triangles are identical so that means
x= 32
so what i did you get 148 is i added 118 and 30 together and then i subtracted 118 from 180 to get 32
i hope this helps
