Answer: The four angles of quadrilateral are [tex]30^{\circ},60^{\circ},150^{\circ}[/tex] and [tex]120^{\circ}[/tex].
Step-by-step explanation:
Let the sides of quadrilateral be x, 2x, 5x and 4x.
We know that, the sum of all angles of quadrilateral = 360°.
[tex]\Rightarrow\ x+2x+5x+4x=360^{\circ}\\\Rightarrow12x=360^{\circ}\\\Rightarrow\ x=\frac{360}{12}\\\Rightarrow\ x=30[/tex]
Then the first angle [tex]x=30^{\circ}[/tex]
The second angle [tex]2x=2\times30=60^{\circ}[/tex]
The third angle [tex]5x=5\times30=150^{\circ}[/tex]
The fourth angle [tex]4x=4\times30=120^{\circ}[/tex]
The four angles of the quadrilateral are 30, 60, 150, 120 degrees.
What is quadrilateral?
A quadrilateral is a closed shape and four-sided polygon.
Which have four angles and four corners.
Given
The four vertices of an inscribed quadrilateral divide a circle in the ratio 1: 2 : 5: 4.
The sum of all the interior angles in a quadrilateral is equal to 360 degrees.
Let the sides of the quadrilateral be x, 2x, 5x, and 4x.
Then,
[tex]\rm x+2x+5x+4x=360\\\\12x=360\\\\x = \dfrac{360}{12}\\\\x=30[/tex]
Therefore,
The four angles of the quadrilateral are;
x = 30
2x = 2(30) = 60
5x = 5(30) = 150
4x = 4(30) = 120
Hence, the four angles of the quadrilateral are 30, 60, 150, 120 degrees.
