To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5

then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5

given the information in this picture which trigonomic identity can be used to solve for the height of the blue ladder that is l

professor190 [17]

Perpendicular=50ft=P
Hypotenuse=h=?

$\\ \tt\hookrightarrow sin\theta=\dfrac{P}{H}$

$\\ \tt\hookrightarrow sin47=\dfrac{50}{h}$

$\\ \tt\hookrightarrow h=\dfrac{50}{sin47}$

$\\ \tt\hookrightarrow h=\dfrac{50}{0.73}$

$\\ \tt\hookrightarrow h=68.4ft$
