Opposite angle of a quadrilateral add up to 180 degrees.
This means Angle A plus Angle C equal 180.
We can solve for X using that, then solve for Angle B.
2x-7 + x +4 = 180
Simplify:
3x -3 = 180
Add 3 to each side:
3x = 183
Divide both sides by 3:
x = 183 /3
x = 61
Now we know x, replace x with 61 in the equation for Angle B:
Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.
Answer:
y + 1 = 4(x - 2)
y = 4x + 11
8x - 2y = 6
Step-by-step explanation:
Following equations are parallel to the graph 4x - y = 6, because their slopes are equal (4).
y + 1 = 4(x - 2)
y = 4x + 11
8x - 2y = 6
The bar between the numerator and denominator of a fraction represent division.
Answer:
64 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the length of the side )
Given
area = 16, then
s² = 16 ( take the square root of both sides )
s = 
= 4 , thus
V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
