Answer:
x = 108°
Step-by-step explanation:
In a trapezoid, each lower base angle is supplementary to the upper base angle on the same side.
72° is a lower base angle and x the upper base angle on the same side, hence
x + 72 = 180 ( supplementary angles sum to 180° )
subtract 72 from both sides, thus
x = 108°
Answer:
D is the correct answer
Step-by-step explanation:
Fifth row of Pascal pyramid is 1 , 5, 10, 10, 5 , 1
The expansion should always have n + 1 number of terms
Where n is the power
Y=x²+8x+14
to make a square, if a is 1, add (half of b)²
in this case, a=1, b=8, half of 8 is 4
y=x²+8x+4²-4²+14
y=(x+4)²-16+14
y=(x+4)²-2
B is the answer.
another way to do it:
the vertex is at x=-b/2a=-8/2*1=-4
when x=-4, y=(-4)²+8(-4)+14=-2
so the equation is y=[x-(-4)]²-2, which is y=(x+4)²-2, the same answer B
