In the case above, the length of Angle DA is 6 and angle ABD ≈ Angle CAD.
<h3>What is the angle about?</h3>
Note that:
Δ ABC , A = 90
To find length of DA :
Let Δ ACB = x
So Δ ABC = 90 -x
For Δ ABC and ADC:
Δ ADB = Δ ADC (90°)
Δ ABD = Δ DAC (90 - x)
For Δ ABC ≈ ADC:

AD² = BD. CD.
AD²= 9 . 4
AD²= 36
AD = 6
Therefore, In the case above, the length of Angle DA is 6 and angle ABD ≈ Angle CAD.

You need to add 38 and 14 together to get answer of 52 years old.
Answer: x = -1
Step-by-step explanation:
(4x + 4) + 4 = 4 subtract 4 from each side
(4x + 4) = 0 subtract 4 from each side again
4x = -4 divide each side by 4
x = -4/4
x = -1
$1,500
P/R $900 net price (P) trade discount rate is 40 percent. Must use
complement (100 percent – 40 percent) since the portion (net price)
represents 60 percent of the list price. $900/.60 = $1,500 (B)
