Answer:
Explanation:
[ Step One ] Factor 
[ Step Two ] Rewrite Equation
[ Step Three ] Factor 
[ Step Four ] Rewrite Equation
[ Step Five ] Cancel Out Common Factor 
The bisector BD is perpendicular to the line segment AC then the angle formed in between is 90°. We can solve for DC using SOH CAH TOA theorem or Pythagorean theorem.
Since ∠BDA is 90°, we can examine that AD is equal to 2units. Proving this, we have BD^2=BD^2+AD^2.
3^2=DB^2+2^2
DB=5units
Therefore, DC=AC-AD and the answer is 2 units.
Answer: the first answer is 8 and 5/8, #2, (bottom left) is 17 and 6/10. #3, (top right) is 6 and 3/8. #4, (bottom right) is 19 and 3/10.
Step-by-step explanation: to add fractions, you have to have a common denominator. to get a common denominator, you multiply one or both sides to make the same number on the bottom. when you multiply the bottom, you also have to multiply the top. After that, you add the top numbers and add the whole numbers next to it. Then you just put the numbers together.
Hope this helps! if it is wrong, could you please correct me.
