Answer:
65 degrees because tangent chord angles are half the size of the arc
To find the area of a square it is length times width, meaning 7*7 would make your area for the square. A triangle's area is found by height*base/2. The height in this situation would equal 4, since they are all identical. The base would be 7 since it is next to the square, meaning you would do 7*4 then divide that answer by 2. You can times the answer of that by three since there is three identical triangles and add the area of the square to that and there is your area! Hope this helps, pretty simple to find once you know how. :)
Answer:
9,000 but Idk if that plus is indicating adding or if it is indicating positive
The answer is B. Since you know the lengths of both legs of the triangle, you can use the Pythagorean Theorem to solve. The Pythagorean Theorem says "a squared plus b squared equals c squared. The square root of c is the length of the hypotenuse." Since there is no answer that says 19.799 (This is the approximate answer), then the answer is B.
