The value of the angle m∠4 is 105 degrees.
<h3>How to find angles in a quadrilateral?</h3>
The sum of angles in a quadrilateral is 360 degrees.
Therefore,
m∠1 + m∠2 + m∠3 + m∠4 = 360°
Hence,
x + x + 10 + x + 20 + x + 30 = 360
4x + 60 = 360
4x = 360 - 60
4x = 300
x = 360 / 4
x = 75
Therefore,
m∠4 = 75 + 30 = 105°

Answer:
x = 7
Step-by-step explanation:
Given is the figure of a kite.
Opposite sides are equal... (given)
Since, measures of the angles opposite to equal sides are equal.
Also, diagonals of a kite interests at right angles.
Therefore,

Therefore,
