Triangle z w x is shown. angle z w x is a right angle. an altitude is drawn from point w to point y on side z x to form a right angle. the length of w x is b, the length of x y is a, the length of y z is 5, and the length of w y is 6. what is the approximate value of b, rounded to the nearest tenth? 7.2 units 7.8 units 8.6 units 9.4 units

7.8 units

Step-by-step explanation:

Since an altitude is drawn form W to Y that length is told to be 6. And length YZ is told to be 5, YX's a would equal 5 as well because the altitude cuts the triangle ZWX in half making right triangle.

Using the Pythagorean theorem +=.

It would be +=

= 7.8 units

(p.s. = 7.8

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

i think the answer would be c
