Answer: 4
Step-by-step explanation:
<u>solve for the missing angle</u>
the total degrees a triangle can have is 180 so
use <u>law of sines</u> to solve for x
cross multiply
divide by
type into calculator with (<em>ALPHA Y= </em>for a fraction on TI-84) MAKE SURE IT IS IN DEGREES
Since a^2+b^2=c^2 becomes 20^2+b^2=29^2, we solve for b:
400+b^2=841
b^2=441
b=21
So the length of b is 21 units.
Hope this helped!
