Unit 8: Right Triangles & Trigonometry
Homework 2: Special Right Triangles

17. z=39/sin45=

    y=39/tan60=

    x=y/sin60=

19. x==6

    y=2x=12

    z=

Step-by-step explanation:

17.

because:sin45=39/z    

so:     z=39/sin45=

then: tan60=39/y

so:    y=39/tan60=

last:  sin60=y/x

so:    x=y/sin60=

19.

because: tan60=/x

so:            x==6

then:        sin30=x/y

so:            y=x*sin30=2x=12

last:          sin45=y/z

so:            z=sin45*y=

the correct answer is c

-1/3(x+1)^5

i’m pretty sure this is correct
