B. In a 30-60-90 triangle, the ratio of the lengths of the sides is 1:\n:2. In other words, the length of the longer leg is\ntimes the length of the shorter leg, and the hypotenuse is twice the length of the shorter leg. Therefore, the smallest side is half the length of the hypotenuse, so its length is\n.\n2. C. The area of a circle is given by the formula A =\n2, where r is the radius of the circle. The problem provides the diameter of the circle, which is twice the radius. So,\nNow substitute this value into the area formula and calculate the area.\n3. D. The perimeter of a figure is the length around it. To find the perimeter of a polygon, add the lengths of its sides. Start by filling in the missing lengths of the sides. For instance, the length of the shorter missing side is 6 because if you add it to the 3 on the left, the result should be the 9 on the right.\nFinally, add the side lengths together to find the perimeter.\n12 + 3 + 9 + 9 + 6 + 3 = 42\n4. D. The sum of the angles of a triangle is 180°. Therefore, if we subtract the two given angles from 180°, the result will be the missing angle.\n180 – 95 – 35 = 50\nTherefore, the missing angle is 50°.\n5. B. The circumference of a circle is given by the formula C = 2\n, where r is the radius of the circle. Substitute the given circumference into this formula and solve for r.\u000b30\n= 2\nr = 15\u000bTherefore, the radius of the circle is 15. Use this to find the area of the circle. The area of a circle is given by the formula A=\n2.  Substitute the length of the radius into this formula and calculate the area.\u000bA =\n(15)2 = 225\n6. B. The sum of the measures of the interior angles of a polygon with n sides is 180 . (n – 2) A hexagon has six sides. Therefore, substitute 6 for n into the formula and calculate.\nTherefore, the sum of the measures is 720°.\n7. A. The area of a triangle is given by the formula\n, where b is the length of the base and h is the triangle’s height. In the figure, the base is 8 and the height is 5. Substitute these values into the formula and calculate the area.\n8. D. In a parallelogram, adjacent angles are complimentary; that is, they add to 180°. Use this to set up an equation, and then solve it for x.\n9. E. If a triangle is a right triangle, then the lengths of its sides satisfy the Pythagorean Theorem, a2 + b2 = c2 . To determine which choice is correct, test each set of values by substituting them into the Pythagorean Theorem. Start with the first set of numbers: 3, 13, and 14.\nSince the result is not a true equality, the first set of values does not represent the side lengths of a right triangle. Test the other four choices. The only values that satisfy the Pythagorean Theorem are 5, 12, and 13.\n10. D. Since the triangle is an equilateral triangle, its angles are 60°. In addition, the vertical line AX bisects the angle BAC, so it splits it into two congruent angles of 30° each. Therefore, the two smaller triangles are 30-60-90 triangles. Thus, the ratio of the lengths of the sides is 1:\n:2. Use this to fill in the information of the figure as follows.\nThe area of a triangle is given by the formula\n, where b is the length of the base and his the height. In the figure, the base is 3 + 3 = 6 and the height is 3\n. Substitute these values into the formula and calculate the area.","cbCainJy85Wwl3ox","https://ap.wps.com/l/cbCainJy85Wwl3ox","docx",324665,"English","# Answer Key\n## Solution Steps by Question","[{\"question\":\"What triangle-specific ratio is used to solve the 30-60-90 triangle problem?\",\"answer\":\"The solutions use the 30-60-90 ratio of side lengths as 1:2 and relate the smallest side to half the hypotenuse and the longer leg accordingly.\"},{\"question\":\"How are circle area and radius determined in the answer key?\",\"answer\":\"The solutions use the circle formulas A=πr² and C=2πr, then substitute given values (such as diameter or circumference) to compute r and finally compute the area.\"},{\"question\":\"How does the key determine the missing angle in the triangle problem?\",\"answer\":\"It uses the triangle angle sum 180°, subtracts the two given angles from 180°, and takes the result as the missing angle.\"}]","answers to review test | DOCX"]
