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
Answer:
the side length is 30 feet
Step-by-step explanation:
we are given cost equation as
where
C is the cost in dollars
n is a side length in feet
we are given
cost is $355
so, C=355
we can set C=355
and then we can solve for n
we can subtract both sides by 175
Multiply both sides by 5
now, we can take sqrt both sides
So,
the side length is 30 feet
Answer:
first one:6.46
second one:7.25
Step-by-step explanation:
for the first one I simply added the two numbers.
for the second one,I divided 66.70 by 9.2
All this means is (f(x)) + (g(x))
2x-1+ x^2-3x-2=
=== x^2 - x -3
