what is the value of c?
4 units
5 units
6 units
7 units

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:

Take square root of both sides:

.

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.
