Question

Im the given figure abcd find the value of x A = 70 B = 80 C = 70 find D the value of x​



please answer who will answer first I will mark as brainliest

Answer 1

Answer:

the answer which I found is 140 degree

Answer 2

Given,

It is given that $\[xA = 70B = 80C = 70D.\]$

Solution,

Know that the sum of all exterior angles of a quadrilateral is $\[360^\circ .\]$

Therefore,

$\[\begin{array}{l} \Rightarrow 70^\circ + 80^\circ + x^\circ + 70^\circ = 360^\circ \\ \Rightarrow 220^\circ + x^\circ = 360^\circ \\ \Rightarrow x = 360^\circ - 220^\circ \\ \Rightarrow x = 140^\circ \end{array}\]$

Hence, the value of $\[x\]$ is $\[140^\circ .\]$
