Anybody know how to do this, it's about angles. ​
gizmo_the_mogwai [7]

Step-by-step explanation:

45°+90°+60°+X°=360° (being complete angle)

or,195°+X°=360°

or,X°=360°-195°

or,X°=165°

Therefore,valueof X is 165°.

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

Easy question for all the points?
kaheart [24]

Answer:

D

Step-by-step explanation:

Height: h

Length: 2h + 15

Area = length × width

4h² + 42h + 90

2(2h² + 21h + 45)

2[2h² + 15h + 6h + 45]

2[h(2h + 15) + 3(2h + 15)]

2(h + 3)(2h + 15)

Width = 2(h+3) = 2h + 6

Length: 2h + 15

Difference:

(2h + 15) - (2h + 6)

2h + 15 - 2h - 6

9

Width is 9 feet shorter than the length
