Unit 8: Right Triangles & Trigonometry<br> Homework 2: Special Right Triangles

Kamila [148]

Answer:

17. z=39/sin45= $78/\sqrt{2}$

y=39/tan60= $39/\sqrt{3}$

x=y/sin60= $78/\sqrt{3}$

19. x= $6\sqrt{3}/tan60$ =6

y=2x=12

z= $\sqrt{2}y=12\sqrt{2}$

Step-by-step explanation:

17.

because:sin45=39/z

so: z=39/sin45= $78/\sqrt{2}$

then: tan60=39/y

so: y=39/tan60= $39/\sqrt{3}$

last: sin60=y/x

so: x=y/sin60= $78/\sqrt{3}$

19.

because: tan60= $6\sqrt{3}$ /x

so: x= $6\sqrt{3}/tan60$ =6

then: sin30=x/y

so: y=x*sin30=2x=12

last: sin45=y/z

so: z=sin45*y= $\sqrt{2}y=12\sqrt{2}$
