The angles are complementary.

This means they add to 90 degrees.

(2x + 1) + (x + 5) = 90.

3x + 6 = 90. (Combine like terms)

3x = 84. (Subtract 6 from each side)

x = 28. (Divide 3 from each side)

x = 28

D is correct

Given that point A is the midpoint of line segment ED, where E( -1,9) and A(4,5), what is the location of point D?
yuradex [85]

Answer:

  D(9, 1)

Step-by-step explanation:

A being the midpoint means its coordinates satisfy ...

  A = (E + D)/2

Solving for D, we find ...

  D = 2A -E

  = 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)

  D = (9, 1)

17) AB = 26

18) ∠1 and ∠2 are supplementary angles.

19) ∠1 and ∠2 are vertical angles.

20) x = 7

21) 10.125° = ∠GEF

22) x = 14

23) x = 25

<h3>How to find congruent angles?</h3>

17) AC is congruent to CE.

DE = 7x - 1

BC = 9x - 2

CE = 10x + 18

DE + DE = CE

2DE = CE

2(7x - 1) = 10x+18

14x-2 = 10x+18

14x-10x = 18+2

4x = 20

x = 20/4

x = 5

Thus; AC = CE = 10x + 18

CD = 10x + 18 - 7x + 1

CD = 3x + 19

AB = 10x + 18 - (9x - 2)

AB = 10x + 18 - 9x + 2

AB = x + 18 + 2

AB = x + 20

Since x = 5

AB = 5 + 21

AB = 26

18) ∠1 and ∠2 are supplementary angles.

19) ∠1 and ∠2 are  vertical angles.

20) ∠TUV = ∠TUW + ∠WUV

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

12x - 20 = 9x + 1

3x = 21

x = 21/3

x = 7

21) Let ∠DEG = x. Thus;

∠GEF = 5x - 13

Thus;

x + 5x - 13 = 149

6x = 162

x = 162/6

x = 10.125° = ∠GEF

22) 7x - 1 + 6x - 1 = 180

13x = 182

x = 14

23) 5x + 4 = 8x - 71

3x = 75

x = 25
