Question
In Exercise I through & change the angles given in degrees and decimal parts of a to degrees to degree and minutes. change the angle given in degrees and minutes to degrees and decimal parts of a degree. 37.5 degree 43.95 degree 12.55 degree 45.27 degree 63.30 degree 82. degree 20' 105 degree 54' 215 degree 45 ' In Exercises 9 through 24, find the perimeters of the indicated geometric figures. Triangle: a = 17.5 in., b = 13.8 in., c = 8.9 in. Quadrilateral a = 22.4 cm, b = 68.5 cm, c = 37.3 cm, d = 29, 9 cm Equilateral triangle:s = 8.5 mm 12. Isosceles triangle: equal sides of 0.38 yd, third side of 0.53 yd Square: s = 6, 8 m Rhombus: side of 15.2 in. Parallelogram: a = 692 ft, b = 207 ft Parallelogram a = 7.8 m, b = 6.2 m Rectangle: l = 96 cm, w = 43 cm Rectangle: l = 108 in., w = 92 in. Circle r = 4.25 ft Circle: d = 38.0 cm The figure in Figure 6.56 (equilateral triangle attached to rectangle). The figure in 6.57 (square and rhombus attached) The figure in Figure 6.58 (rectangle with a half circle removed). The figure in Figure 6.58 (rectangle with a triangle and half circle removed). In exercise 25 through 40 find the area of the given figures.Explanation / Answer
2 ) 43.95° = 43 ° + .95 °
1° = 60'
.95° = 60 * .95 =57'
43.95° = 43°.57' (43 degrees and 57 minutes )
7 ) 105° 54' = 105° + 54'
1' = (1/60)°
54' = 54/60 = .9°
105° 54' = 105.9°
19) Perimeter of a circle is given by 2R
R=4.25ft
Perimeter = 2* 4.25
= 8.5 ft
20 ) Diameter = 38 cm
R= 38/2 =19cm
Perimeter = 2* 19 cm
= 38 cm
