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

That's all (I think)! Hope this helps! :)
2x-1=7x+44 is equal to -9. The first step is to add one on both sides to get x by itself. Right now you should have 2x= 7x+45. Then you subtract 7x from both sides. You should have -5x=45. Now divided -5 on both sides. You should get the answer x=-9. By the way remember only subtract variables from other variable and regular numbers only from other regular numbers. Hope this helps, if you have any questions please comment.
