First let's find the mesure of the missing ANGLE: Missing angle = 180° - (42°+ 87°) = 51°

cos 51° = (adjacent side)/(hypotenuse) = x/43
<u />0.629320.91 = x/43
and x = 27.1

We know

$\boxed{\sf cos\Theta=\dfrac{b}{h}}$

$\\ \sf\longmapsto cos22=\dfrac{x}{47}$

$\\ \sf\longmapsto 0.9=\dfrac{x}{47}$

$\\ \sf\longmapsto x=47(0.9)$

$\\ \sf\longmapsto x=42.3$

11 + 5 = 16

264 + 16 = 280

280 - 10 = 270

270 is your answer
