Answer:
Therefore,
Step-by-step explanation:
Given:
DF bisects ∠ EDG
EF = n +5
GF = 2n - 6
To Find:
GF =? or
EF =?
Solution:
In ΔDEF and ΔDGF
∠E ≅ ∠G ……….{Measure of each angle is 90° given}
∠EDF ≅ ∠GDF ………..{ DF bisects ∠ EDG }
DF ≅ DF ……….{Reflexive Property}
ΔDEF ≅ ΔDGF ….{ By Angle-Angle-Side Congruence Postulate}
∴ EF ≅ GF ..{Corresponding Parts of Congruent Triangles are Congruent
}
Substituting the values we get
Substituting 'n' in EF and GF we get
Therefore,
Answer:
Step-by-step explanation:
4) Given that 3x<15
Divide by +3 without affecting inequality
x<5
Hence answer is (-∞,5)
5) -6x<18
Add 6x to both sides
0<6x+18
Subtract 18
-18<6x
Divide by +6
-3<x
Hence answer is (-3,∞)
6) 2x+6>x-7
Subtract x-6 from both the sides
x >-13
So answer is (-13,∞)
7) -4x+8≥14
Add 4x-14 to both the sides
-6≥4x
x≥-3/2
Hence answer is [-3/2,∞)
