Answer:
BD = 3 units
Step-by-step explanation:
Since, AD is an angle bisector of ∠BAC,
m∠BAD = m∠CAD = 20°
CD = 3 units
In ΔACD and ΔABD,
m∠BAD = m∠CAD = 20° (Given)
AD ≅ AD [Reflexive property]
Therefore, by H-A property of congruence both the triangles will be congruent.
And by CPCTC,
CD ≅ BD = 3 units
Answer:
20
23 is between 20 and 30, but it's closer to 20. So 23 is rounded down to 20.
4
one of the functions equals 0 while the other equals 4
0+4=4
Answer:
<h2>x = 3.499 in</h2>
Step-by-step explanation:
In a kite, the diagonals are perpendicular. Hence
