A vertical line has an undefined slope.
vertical lines are X= something
in this case it needs to intercept 9.
so it is X=9
<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
</span>1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle<span>
if sum < 3rd side² Obtuse Triangle
1) 1,296 2,401 3,600
2) Sum = 3,697
3) </span><span>3,697 is greater than 3,600
Therefore, the triangle is acute.

Step-by-step explanation:
congurency property can be used for all right angles triangles
that's all ....have fun
Recall that i represents the square root of -1, so by squaring it we get -1.
(2 + 4i)(7 - 3i)
= 14 - 6i + 28i + 12
= 26 + 22i
I think the answer is 6 if i'm not mistaken.
