The sum of three numbers is 72
LekaFEV [45]

Answer: <u><em>The first number is 8</em></u>

Step-by-step explanation: Let the three No. s be x, y and z respectively

given = x+ y+ z= 72

y=7x

z=7x-18

∴As we know x+ y+ z=72

i.e. x+7x+7x-18=72

15x=72+18=90

15x=90

x=90/15

∴x=8

∴y=7x

7×8=56

∴z=7x-18

56-18=38

∴<u><em>The first no. is x=8</em></u>

<u><em>The second no. is y=7x = 56</em></u>

<u><em>The third no. is z=7x-18 = 38</em></u>

Given: △ABC, BC&gt;AC, D∈ AC , CD=CB Prove: m∠ABD is acute
Aleksandr [31]

Answer:

Step-by-step explanation:

Given: △ABC, BC>AC, D∈ AC , CD=CB

To prove: m∠ABD is acute

Proof: In ΔABC, the angle opposite to side BC is ∠BAC and  the angle opposite to side  AC is ∠ABC.

Now, it is given that  BC>AC, then ∠BAC>∠ABC..                       (1)

In ΔBDC, using the exterior angle property,

∠ADB=∠DBC+∠BCD

∠ADB=∠DBC+∠BCA

⇒∠ADB>∠BAC                            (2)

From equation (1) and (2), we get

∠ADB>∠BAC

⇒∠ADB>∠ABC

⇒DB>AB

Hence,    m∠ABD is acute
