Step-by-step explanation:
Let's solve for y.
9x+6y=27
Step 1: Add -9x to both sides.
9x+6y+−9x=27+−9x
6y=−9x+27
Step 2: Divide both sides by 6.
6y
/6=−9x+27

Answer:
A
Step-by-step explanation:
<u>Answer</u> : The demonstration is below :)
Step-by-step explanation :
<u>We use Pythagoras' </u><u>theorem </u><u>:</u>
- In the triangle ABC we have :
AB² = AC² - BC² = 15² - 9² = 144 = 12²
- In the triangle ABD we have :
DB² = AD² - AB² = 13² - 12² = 5²
cos(a) = BD/AD = 5/13
