Answer:

19 degrees

Step-by-step explanation:

From the question given

The interior angles are x+12 and x - 3

Exterior angle is <IJK = 5x-6

Using the rule that states that the sum of interior angle of a triangle is equal to the exterior

<JHI + <HIJ = <IJK

x+12 + x-3 = 5x - 6

2x+9 = 5x -6

2x - 5x = -6-9

-3x = -15

x = -15/-3

x = 5

Get <IJK

Recall that <IJK = 5x - 6

<IJK = 5(5) - 6

<IJK = 25-6

<IJK = 19 degrees

Hence the measure of <IJK is 19 degrees

The question is in the picture:
rosijanka [135]

Answer:

  b) The measure of angle B is 117°.

Step-by-step explanation:

Angles A and C are vertical angles, so are congruent. Angles C and 27° total 90°, so ...

  ∠C = 90° -27° = 63° . . . . . not 53°

The measure of angle B is the supplement of angle A or C, so is ...

  ∠B = 180° -∠C = 180° -63°

  ∠B = 117°

Only choice B is correct.

Answer:

  • x = 15

Step-by-step explanation:

<u>Since the quadrilateral is inscribed into circle, its opposite angles are supplementary:</u>

  • m∠H + m∠K = 180°

<u>Substitute the values and solve for x:</u>

  • 5x - 22 + 8x + 7 = 180
  • 13x - 15 = 180
  • 13x = 195
  • x = 195/13
  • x = 15
