Write down the supplements of one half of a right angle, four thirds of a right angle, also of $46°,102°{15}^{|},96°{54}^{|}$ .

i) One half of a right angle $=\frac{90°}{2}=45°$

supplement of $45°=180°-45°=135°$

ii) four thirds of a $90°=\frac{4}{3}\left(90°\right)=120°$

supplement of $120°=180°-120°=60°$

iii) supplement of $46°=180°-46°=134°$

iv) supplement of $120°{15}^{|}$

$=180°-120°{15}^{|}$

$=179°{60}^{|}-120°{15}^{|}$

$=59°{45}^{|}$

V) supplement of $96°{54}^{|}$ $=180°-96°{54}^{|}$ $=179°{60}^{|}-96°{54}^{|}=83°{06}^{|}$
