Here’s Question three

Hitman42 [59]

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

use the value of the ratio to determine which ratio is equivalent to 7:15. Check all that apply! Question 4 options: 21:45 14:45

PIT_PIT [208]

7:15=(7*3):(15*3)=21:45

7:15=(7*9):(15*9)=63:135
