Answer 1

Answer:

$x = 7 \sqrt{2}$

Step-by-step explanation:

$sinθ = \frac{opp}{hyp}$

$sin45° = \frac{7}{x}$

$\frac{ \sqrt{2} }{2} = \frac{7}{x}$

Cross multiply:

$( \sqrt{2} )(x) = 7(2)$

$x = \frac{14}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} }$

$x = \frac{14 \sqrt{2} }{2}$

$x = 7 \sqrt{2}$
