Answer:
5 units
Step-by-step explanation:
You could use the Pythagorean Theorem since triangle WYZ is a right triangle. We know it is right because angle WYZ has the little square there meaning 90 degree measurement at that angle.
So the two legs have measurements 4 and 3.
We need to find the hypotenuse. We know c represent the hypotenuse measurement because it is opposite the 90 degree angle.
We need to solve:
[tex]4^2+3^2=c^2[/tex]
[tex]16+9=c^2[/tex]
[tex]25=c^2[/tex]
Take square root of both sides:
[tex]5=c[/tex].
Eventually you will start to remember (3,4,5) has a Pythagorean triple where the smaller measurements in the triple represent leg measurements while the largest represents the hypotenuse.
