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
Answer:
x=3
Step-by-step explanation:
y= -2
4x-3y=18
4x-3(-2)=18
4x-(-6)=18
4x+6=18
4x+6-6=18-6
4x=12
x=3
If its helpful ❤❤❤
THANK YOU
Answer:
x <= -51/5
First option
Step-by-step explanation:
GCM = 28
4(x-4) - 2(x+7) >= 7(x+3)
Distributive property
4x-16 -2x - 14 >= 7x + 21
2x - 30 >= 7x + 21
- 5x - 30 >= 21
-5x >= 51
x <= -51/5 (divide a negative number, flip the sign)
Answer
x <= -51/5
