1) Answer: x = 9

<u>Step-by-step explanation:</u>

Same Side Interior Angles are supplementary

15 + 5x + 14x - 6 = 180

19x + 9 = 180

19x = 171

x = 9

***************************************************************

2) Answer: x = 9

<u>Step-by-step explanation:</u>

Corresponding Angles are congruent

13x - 7 = 11x + 11

2x = 18

x = 9

***************************************************************

3) Answer: x = -10

<u>Step-by-step explanation:</u>

Alternating Interior Angles are congruent

90 = x + 100

-10 = x

***************************************************************

3) Answer: x = 7

<u>Step-by-step explanation:</u>

Alternating Exterior Angles are congruent

17x + 1 = 120

17x = 119

  x = 7

Hello! can you please, help me by finding some missing angles.
yuradex [85]

Answer:

Going horizontally,

Q1 a) x = 133°

Q1 b) x = 59°

Q1 c) x = 189°

Q1 d) x = 32°

Q1 e) x = 72°

Q1 f) x = 36°

Q2 a) x = 53°

Q2 b) x = 94°

Q2 c) x = 10°

Workings out:

To work out the interior angles, you need to know that angles on a straight line add up to 180°. In addition, you also need to know that angles around a point add up to 360°. When you need to find a missing angle, if the angle is on a line or in a triangle, take whatever value/values the angle/angles you have are and take it away from 180°. If the angle is around a point, (or in a square, where all angles are the same anyway) add however many values you have for the angles then take that away from 360°. Hope this helps! :)
