Supplementary angles are angles that add up to 180 degrees. Oftentimes, we see that supplementary angles are on a straight line, of which is also equal to 180 degrees.
x + y = 180
x + 116 = 180
x = 64 degrees
Hope this helps!! :)
Answer:
864 in^2
Step-by-step explanation:
Area of triangle
15 x 18 x 1/2 = 135
Area of Square
18 x 18 = 324
There are 4 triangles so...
135 x 4 = 540
Therefore the area is
540 + 324 = 864
2.89
This is 289% as a decimal.
100%s are 1s, so
200% = 2
