Question

Find the measure of all unknown angles in each of the following :

Answer 1

(a) $b^0+{110}^0={180}^0$ [Supplementry]

$\Rightarrow \measuredangle b={70}^0$

Similarly, $a^0={80}^0$

$a^0+b^0+c^0={180}^0$

$\Rightarrow c^0={30}^0$

$\therefore$ $d^0={150}^0$

(b) $p+{132}^0+{142}^0={360}^0$

$\Rightarrow p={86}^0$

$p+50+q={180}^0$

$\Rightarrow q={44}^0$
