Answer:
<em>4 and 1 / 3 cm</em>
Step-by-step explanation:
Consider the following;

Let us say that Height = x. If that is so, through algebra, let us solve for x;

<em>Solution ⇒ 4 and 1 / 3 cm</em>
Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
Answer: The answer would be -13! :)
Explanation:
5(-2) - 3(2) - (-3)
-10 - 6 + 3
-16 + 3
-13
140.4 since the sides are equal . Iguess . I did not calculate or anything but mentally
