20. Using a trigonometric ratio, what is the value of x rounded to the nearest tenth? The figure not drawn to scale 15* 12 x 46.4 Ox=44 8 O,-12.4 x-32 21. What is the value of x to the nearest degree? The figure is not drawn to scale (1 point) 10 x= 61 x=31 22. What is the area of a regular hexagon with side length of 8 cm to the nearest tenth? (1 point) O55.4 cm 01663 cm2 91920 cm O 3326 cm? (1 po 23. The trapezoids shown below are similar but not drawn to scale Type here to search

Solution

20. ) option : second , x = 44.8

Explanation:

??tan (15) = (12) / (x) => x = (12)/ [tan ( 15) ] => x = 44.8

21) option : second , x = 59

Explanation:

tan (x) = (10) / (6) => x = arctan [ (10) / (6) ] => x = 59

22)option : second ,166.3 cm²

Explanation:

?Area of regular hexagon of side a = 3 * a²? * sin (60)

here a = 8 cm

So, Area of regular hexagon = 3 * 8^?2? * sin (60) = 166.3 cm²
