Answer:
the two angles of dark green triangle are 90 degrees, 72 degrees and 18 degrees.
Step-by-step explanation:
As dark green triangle is stacked on top of light green triangle and one side of dark green is sharing hypotenuse of light green, considering both have same area, mean same 1/2 base* height ,also one leg of both is same so its obvious that both heights and bases of triangles are same. Considering all the above facts both triangles are forming a square with common side as diagonal of square.
So, the angles of light green triangle are 90 , 18 and (180-90-18)=72 degrees
One angle of dark green is already 90 degrees , the other two combined with light green form 90 degrees (as both are side angles of square).
90-18=72
90-72=18
Hence the three angles of dark green triangle are 90,72 and 18.
Answer:
Yes you would know
Step-by-step explanation:
We can view these tents as sides on a shape that is 30 sided, with lines connecting each tents together.
After this we calculate the interior angle of each side, and use our given 20m to calculate it.

A tangent meets with the radius to form a right angle
Thus, we can use Pythagoras' theorem
b^2 = c^2 - a^2
Sub the values in:
b^2 = 5^2 - 3^2
b^2 = 16
Square root for the answer:
b = 4
Thus, the answer is option A.
