Consider kite WXYZ.
kondaur [170]

Answer:

  • a = 8; b = 40

Step-by-step explanation:

<em>See attached</em>

<h3>Given </h3>

<u>Kite WXYZ with:</u>

  • XY = 3a - 5
  • YZ = a + 11
  • ∠W = 50°
  • ∠X = 3b
  • ∠Y = 70°
<h3>To find </h3>
  • Values of a and b
<h3>Solution</h3>

<u>Since XY and YZ are congruent sides, XY = YZ</u>

  • 3a - 5 = a + 11
  • 3a - a = 11 + 5
  • 2a = 16
  • a = 8

<u>The angles Z and X are equal and the sum of 4 angles is 360°, therefore:</u>

  • 3b + 3b + 50° + 70° = 360°
  • 6b + 120° = 360°
  • 6b = 240°
  • b = 40°

<u>Correct option is the last one </u>

  • a = 8; b = 40°

A puzzle in the form of a quadrilateral is inscribed in a circle. The vertices of the quadrilateral divide the circle into four
e-lub [12.9K]

Answer:

Therefore,

∠A = 30°

∠B = 60°

∠C = 150°

∠D = 120°

Step-by-step explanation:

Given:

A puzzle in the form of a quadrilateral is inscribed in a circle.

The vertices A ,B ,C ,D of the quadrilateral divide the circle into four arcs in a ratio of 1 : 2 : 5 : 4.

Let the common multiple be "x" then the angles will be

∠A = 1x

∠B = 2x

∠C = 5x

∠D = 4x

To Find:

The angle measures of the quadrilateral = ?

Solution:

In a Quadrilateral inscribed in a Circle,

Sum of the measure of all the angles in a Quadrilateral is 360°

m\angle A +m\angle B +m\angle C +m\angle D=360

Substituting the values we get

x+2x+5x+4x=360\\\\12x=360\\\\x=\dfrac{360}{12}=30

Therefore the measures are

∠A = 30°

∠B = 2 × 30 = 60°

∠C = 5 × 30 = 150°

∠D = 4 × 30 = 120°

Therefore,

∠A = 30°

∠B = 60°

∠C = 150°

∠D = 120°
