i think it is 7.5
Answer:
x=3
Step-by-step explanation:
The triangle has angles 30,60,90
In this type of right triangle, the ratio of the sides is 1:square root of 3:2
In this type of triangle, the square root of 3 is equal to the 1 in the ratio above because it is across from the angle 30
With this, we multiply the ratio at the top by the square root of 3
since x is across the angle 60, we multiply square root of 3 by the square root of 3 which equals 3.
I hope this makes sense
Hey there!

Answer:
x = 105 degrees.
Step-by-step explanation:
The small polygon is a regular hexagon so each internal angle = 120 degrees while the large polygon is a regular octagon with internal angle =
135 degrees.
So angle x = 360 - ( 120 + 135)
= 360 - 255
= 105 degrees.
Note we use the fomula T = 180( n - 2) to find total internal angles in an n sided polygon. So for hexagon T = 180(6-2) = 180*4 = 720 so each internal angle in a regular hexagon = 720/6 = 120 degrees.
