If δywz ~ δyxw, what is true about xwz?

a. xwz is an obtuse angle.

b. xwz is a right angle.

c. xwz is congruent to wxy.

d. xwz is congruent to xzw.

If , then

Consider angle XWZ:

.

Since , then

.

Now consider the right triangle XWY. The sum of measures of all angles of triangle is equal to 180°, so

Substitute this expression into expression (*):.

correct choice is B.

b. hannah is playing with her cousin at

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
