Answer:

200cm2=12b×h=12b2 ∵ h=b

⇒b=20cm

Once again, 200=12b×h=1220×csin45

200×2×√220=c

alukav5142 [94]

Answer:

$\huge{ \boxed{ \tt{ \frac{ 7}{4} }}}$

Step-by-step explanation:

$\text{Let \: the \: points \: be \: A \: and \: B}$

$\sf{A \:( \: 0 \:, - 5 \: ) \longrightarrow{ \: (x1 \:, y1)}}$

$\sf{B(4 \:, 2) \: \longrightarrow{ \:( x2 \:, y2)}}$

$\underline{ \text{Finding \: the \: slope} }:$

$\boxed{ \sf{Slope = \frac{y2 - y1}{x2 - x1}}}$

$\sf{➳ \: Slope = \frac{2 - ( - 5)}{4 - 0}}$

$\sf{➳ \: Slope = \frac{ 2 + 5}{4} }$

$\sf{➳ \: Slope = \frac{7}{4} }$
