Answer:

104

Step-by-step explanation:

yz(x + y) - x² when x = 4, y = 2, z = 10

~Substitute

(2)(10)(4 + 2) - 4²

~Simplify

20(6) - 16

~Multiply

120 - 16

~Subtract

104

Best of Luck!

Check the picture below

and recall that

$\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad
cos(\theta)=\cfrac{adjacent}{hypotenuse}\\\\
-------------------------------\\\\
sin(75^o)=\cfrac{y}{8}\implies 8sin(75^o)=y
\\\\\\
cos(75^o)=\cfrac{x}{8}\implies 8cos(75^o)=x$
