Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.
If all of the side are equal, that would mean that it is an equilateral triangle. Meaning all of the angles are the same measure. A triangle equals 180 deg. So you divide that by 3 to find each individual side of the equilateral triangle. Therefore m3=60 degrees.
Hope this helps if not i'm sorry
Answer: 60
Step-by-step explanation:
Using Heron's formula, we know that
Step 1: Calculate "s" (half of the triangles perimeter):
s = (a+b+c)/2
Step 2: Then calculate the Area:
Herons formula A = sqrt( s(s-a)(s-b)(s-c) )
So S = 36/2 = 18
so
So our final answer is the square root of 3600, which equals 60.
