Question

Hw 43 special right triangles

Answer 1

Answer:

Step-by-step explanation:

Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2

we have answers as

8. u=16 and v = $8\sqrt{3}$

9) y=5 and x=$5\sqrt{3}$

10) tan 30 =$\frac{1}{\sqrt{3} }$

So y=$4\sqrt{3}$

x=$8\sqrt{3}$

11) a=22 and b=11

12) b=1.5 and a=$1.5\sqrt{3}$

13) y=$20\sqrt{3}$

and x=10
