Answer:
see below
Step-by-step explanation:
1. m∠DEF = m∠_FEK___ = 44° = Def. of ∠ bisector
2. m∠DEK = m∠_DEF___+m∠FEK___= _angle addition postulate________________
3. m∠DEK = _44___ + _44___ = 88° = Substitution, Algebra
4. DE = _KE____ = Given
5. EF = _FE____ = Reflexive property
6. △DEF ≅ △_KEF____ = _SAS postulate________________
7. DF = FK_____ = ___CPCTC (corresponding parts of congruent triangles are congurent)______________
8. KF = 1/2DK =8 _____ = Algebra, 7
-7(5x-8)
=-35x + 56
which is basically 56-35x if u swap it around
I don’t really know what you mean here but i guess you mean f(x)=2x+3=0
In that case:
F(x)=2x+3=0
Subtract 3 from both sides:
F(x)=2x=-3
Divide both sides by 2:
F(x)=x=-3/2.
Answer:
y = 9
Step-by-step explanation:
m<1 + 2x = 180° because these angles are supplementary
61° + 2x° = 180°
2x = 180 - 61
2x = 119 divide both sides by 2
x = 59.5
Since f is parallel to s:
2x + (7y-2) = 180°
2×59.5 + 7y - 2 = 180
119 + 7y - 2 = 180
7y = 180 - 117
7y = 63 divide both sides by 7
y = 9
Answer:
38 ft.
Step-by-step explanation: (12 x 2) + (7 x 2) = 38 ft.
