The answer is: The first triangle. The reasons are shown below:
1. All the triangles are rigth triangles, because they have an angle of 90°. So, let's calculate the others angles of the first one:
Tan(α)^-1= opposite leg/adjacent leg
Opposite leg=5
Adjacent leg=5√3
Tan(α)^-1= 5/5√3
Tan(α)^-1=30°
2. Let's calculate the other angle:
Tan(α)^-1= opposite leg/adjacent leg
Now, the opposite leg will be 5√3 and the adjacent leg will be 5. Then:
Tan(α)^-1= 5√3/5
Tan(α)^-1=60°
As you can see, the angles of first triangle are: 30°,60° and 90°.
Work:
624 divided by 12 equals 52
answer:
52 dozens
I am so sorry if I'm wrong, but I think 5 is b
Answer:
x = 55°
Step-by-step explanation:
From given figure we have
Two lines parallel
As we know simple straight line maintain an angle of 180°
Third line bisecting the two parallel lines at different position
But hold same same angle form both because lines are parallel.
To find angle = 180 - 125 = 55
Answer:
all regular polygons are symmetrical!!
