Question

Construct a $△$STU in which $T={60}^o$, $U={70}^o$ and $TU=7.5cm$.

Answer 1

$\angle S={180}^{\circ }-({60}^{\circ }+{70}^{\circ })$

$={180}^{\circ }-\left({130}^{\circ }\right)$

$={50}^{\circ }$

For construction:

Draw TU=7.5cm make from T with respect to TU,make from U with respect to

TU,the point where the two lines meet is S.
