Question

IF ANGLE A =40 ANGLE C =60 AND ANGLE D = 50 FIND X IN 5 SIDED PLYGON​

Answer 1

Anѕwєr :-

Here, we can see that angle $B$ and angle $E$ are same and are defined as $x$,

Measure of $B$ and $E$;

$\tt40 + x + 60 + 50 + x = 360 \\ \\ \to \tt \: 2x + 150 = 360 \\ \\ \to \tt \: 2x = 360 - 150 \\ \\ \to \tt \: 2x = 210 \\ \\ \to \tt \: x = \frac{210}{2} \\ \\ \to \tt \: x = 105$

Hence, measure of angle $B$ and $E$ will be 105°.
