Question

* find the x in the given factor ​

Answer 1

answer : 180°-(70°+40°)

= 180°- 110°

= 70°

therefore X = 70°

as all are in a straight line therefore we added the given degrees and substracted it with 180° .

HOPE IT HELPS YOU!

$\sf \large here : \\ \bf 70\degree + x + 40 \degree = 180 \degree \\ ( \sf straight \: line) \\ \bf x + 110 = 180 \\ \bf x = 180 - 110 \\ \bf x = \underline{ \underline{70 \degree}}$
