Help me answer thw following.

If an angle other than an integral multiple of 90 is in standard position, then the positive acute angle between the x-axis and the terminal side of the given angle is called the referenc angle = 150' reference angle = 30" X Give the corresponding reference angle for each of the following. 1. 600 2. 1350 3. 2100 4. 3000 5. -410B. Fill in the blanks by coordinate of the intersection of the terminal sides. converting the degree measures to radians. Then find the (0, 1) 1200 90 1350 600 150 450 300 (-1, 0) 180 09 (1, 0) 2100 2250 330 240 315 300 270 (0, -1)Solve the following problems. 1. In a circle of radius 7 feet, find the length of the arc that subtends a central angle of 5 radians. 2. A central angle 0 in a circle of radius 20 m is subtended by an arc of length 15m m. Find the measure of 0 in degrees. 3. Find the area of the sector with central angle that measures 750 if the radius of the circle is 6 m. 4. A central angle @ in a circle of radius 9 m is subtended by an arc of length 12 m. Find the measure of 0 in radians. 5. A frequent problem in surveying city lots and rural lands adjacent to curves of highways and railways is that of finding the area when one or more of the boundary lines is the arc of a circle. Approximate the total area of the lot shown in the figure. 40 m 60 30 m PAGE 1
