Question

SOMEONE HELP ME PLS I NEED HELP

Answer 1

Answer:

$m\angle{W} = {75{^\circ}}$

$m\angle{Y} = {15{^\circ}}$

$m\angle{Z} = {90{^\circ}}$

Step-by-step explanation:

All angles in a triangle must add up to $180{^\circ}$

First we can use an equation to find $x$

$(x - 15) + (2x - 165) + 90 = 180$

$3x - 180 = 90$

$3x = 270$

$x = 90$

Now we can solve for $\angle W$and $\angle Y$ through substitution

$\angle{W} = 90 - 15 \rightarrow \boxed{75{^\circ}}$

$\angle{Y} = 2x - 165 \rightarrow 2(90) - 165 \rightarrow 180 - 165 \rightarrow \boxed{15{^\circ}}$

Now we can classify the triangle

It is right because it has a $90{^\circ}$ angle

These are the answers
