Answer:

BC = 3.6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BC}{DE}$ = $\frac{AC}{AE}$ , substitute values

$\frac{BC}{1.2}$ = $\frac{4.5}{1.5}$ ( cross- multiply )

1.5 BC = 5.4 ( divide both sides by 1.5 )

BC = 3.6

I forgot what they’re called but the angles opposite to each other are the same degree. It’s a theorem, just search up the name

Answer:

$the \: answer \: is \: c \: = - \frac{ \sqrt{14} }{5}$

Step-by-step explanation:

$\sin^{2}0 + ( \frac{ \sqrt{11} }{5} ) ^{2} = 1( \sin^{2}0 + \cos^{2} 0 = 1)$

${ \sin }^{2}0 + \frac{11}{25} = 1 \\ { \sin }^{2}0 = \frac{14}{25}$

$\sin0_{1} = - \frac{ \sqrt{14}}{5} while \sin0_{2} = \frac{ \sqrt{14} }{5}$
