Tan 18 = opposite side/adjacent side

0.3249 = 4/adjacent side

and adjacent side = 4/0.3249 = 12.31

Now let's apply Pythagoras to find x

4² + 12.31² = x²
16 + 151.55 = x²   and x² = 167.55 
Then x = √167.55 and x = 12.94 ≈ 13

The midpoint of AB is M(1, 3). If the coordinates of A are(4,1), what are the coordinates of B?
Oxana [17]

Answer:

B(-2,5)

Step-by-step explanation:

\frac{x + 4}{2}  = 1 \\ 2 \times  \frac{x + 4}{2}  = 1 \times 2 \\ x + 4 = 2 \\ x = 2 - 4 \\ x =  - 2 \\  \frac{y + 1}{2}  = 3 \\ 2 \times  \frac{y + 1}{2}  = 3 \times 2 \\ y + 1 = 6 \\ y = 6  -  1 \\ y = 5

Hope that this is helpful.

Have a nice day.
