Answer:

Step-by-step explanation:

20) Angles 1 and 2 are supplementary angles( sum of angle 1 and angle 2 is 180 degrees)

21) Angles 1 and 2 are supplementary angles( sum of angle 1 and angle 2 is 180 degrees)

22) Angle TUW + Angle WUV =Angle TUV

Therefore

(7x-9) + (5x - 11) = (9x+1)

7x-9 + 5x - 11 = 9x+1

7x +5x-9x =1 + 11 + 9

3x = 21

x = 21/3= 7

23) GEF - 13 = 5DEG

and DEF = 149 degrees

GEF = 5DEG + 13

Sum of angles (GEF + DEG)=DEF

Therefore,

DEG + 5DEG - 13 = 149

6DEG = 149 + 13 = 162

DEG = 162/6 = 27

GEF = 5DEG = 27 × 5 =135

24) 7x - 1 + 6x -1 = 180(sum of angles in a straight line)

13x-2 = 180

13x = 180+2 = 182

x = 182/13 = 14

25) 5x + 4 + 8x - 7 = 180( sum of supplementary angles is 180)

13x = 180+7-4= 183

x = 183/13 = 14.08
