Answer:
The value of AD=1 and DC=3
Step-by-step explanation:
Given: ΔABC, D∈ AC m∠ABC=m∠BDA, AB=2, AC=4
Diagram: Please find attachment.
To find: AD=? and DC=?
Calculation:
In ΔABC and ΔADB
∠ABC=∠ADB (Given)
∠A=∠A (Common)
Therefore, ΔABC ≈ ΔADB by AA similarity
If two triangles are similar then ratio their corresponding sides are equal
Therefore,

where, AD=?, AB=2, AC=4


AD=1
AD+DC=AC
1+DC=4
DC=4-1
DC=3
Hence, The value of AD=1 and DC=3
A is the right answer
This is because when plugged into each of the expressions, the both equal the same thing. Which means that this proves that the two hypotenuses are congruent, proving the triangles congruent by HL. <span />

Answer:
24
Step-by-step explanation:
hello
let's note x the number we are looking for

so 1/3 of it equals

another way to see it is that 12=4*3
so 1/3 of it equals 6*4=24
hope this helps
