It's a bit of a bummer to have to work through all of these to find the answer. That a lot of slope calculations (or graphing, or whatever). When there are this many, a spreadsheet or other machine help can make it easier.

The correct choice is the last one, XYZ, with vertex X being where the right angle is located.

_____
Slope of XY is 4/7; slope of XZ is -7/4. The product of these is -1, so those segments are at right angles.

What the correct answer now fast

netineya [11]

Answer:

112.065

Step-by-step explanation:

so divide the triangle in two from x to wy

and you get to triangles

then using the first right angled triangle you can apply tan=opposite/adjacent

to get height as 7.56 then apply 1/2bh to get first area as 58.59

first add all angles and subtract from 180=24

then use tan to get the height as 6.9

then apply 1/2bh to get second area as 53.48

then add the two areas to get total

(after getting first one don't multiply by two)
