So what we can assume from the things given,
m∠A = x
<span>
</span>m∠B = 2x
m∠C = 3x
m∠C + m∠B + <span>m∠A = 180º
x = 30º
Because 30º + 60º + 90º = 180º

Answer:
96cm3
Step-by-step explanation:
formula is
v=1/3×area of the base×height
area of base which is a square=l×l
which is equal to 6×6=36
therefore
v=1/3×(6×6)×8
=96cm3
I hope it helps
Answer:
y = 2/3x +4
Step-by-step explanation:
The y intercept is where the line crosses the y axis
y intercept =4
We can find the slope using two points on the line
(0,4) and (3,6)
m = (y2-y1)/(x2-x1)
= (6-4)/(3-0)
= 2/3
The equation of a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 2/3x +4

Answer:
B. neither perpendicular nor parallel
Step-by-step explanation:
If the lines were perpendicular, the coefficients would be swapped and one negated. (You would have 8x -y = c, or 9x +2y = c in the system.)
If the lines were parallel, the coefficients in the two equations would only differ by a common factor. (Both equations would reduce to 2x -9y = c, or x +8y = c.)
The lines are not the same line (coefficients are different).
So, the only reasonable description is ...
neither perpendicular nor parallel
