Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet

Answer:
14.3%
Step-by-step explanation:
1/7=0.142857142857
round that to the nearest tenth and that is 0.143
make it a percentage and it is 14.3%
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then

We know that,


After
rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.
Adjacent angles are angles that have a common side and a common vertex. The only one that fits this would be <FEC and <FEH because it shares the side of FE and common vertex of E. I hope this helps you. :)
