answer :

A. 100

step by step calculation

exterior angle plus interior angle add up to 180 degrees

hence:

180-70=110

180-60=120

180-50=130

therefore 100 is not an exterior angle of that triangle

Step-by-step explanation:

$A = lw \nl\frac{\dA}{\dt}$ = $\frac{\dA}{\text{d}l}\frac{\text{d}l}{\dt} + \frac{\dA}{\text{d}w}\frac{\text{d}w}{\dt}$ = $w\frac{\text{d}l}{\dt} + l\frac{\text{d}w}{\dt}$ $\nll = 20 \text{ cm}$ \;\; $\frac{\text{d}l}{\dt} = 8 \text{ cm/s}$ \;\;w = 10 \text{ cm}, \;\; $]\frac{\text{d}w}{\dt} = 3 \text{ cm/s}$ $\nl\frac{\dA}{\dt} =( 10 \text{ cm} )( 8 \text{ cm/s} ) + ( 20 \text{ cm} )( 3 \text{ cm/s} ) =140 \text{ cm}^2\!\text{/s}
