Answer:

(0.5, 0.5)

Step-by-step explanation:

Use the midpoint formula: $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

The points are:

A(-2, 4)
C(3, -3)

$(\frac{-2+3}{2},\frac{4-3}{2})\\\\(\frac{1}{2},\frac{1}{2})$

Therefore, the midpoint between A and C is located at (0.5, 0.5).

Instructions: Find the lengths of the other two sides of the isosceles right triangle below.

Alexandra [31]

Given:

The ratio of 45-45-90 triangle is $x:x:x\sqrt{2}$ .

The hypotenuse of the given isosceles right triangle is $7\sqrt{2}$ .

To find:

The lengths of the other two sides of the given isosceles right triangle.

Solution:

Let $l$ be the lengths of the other two sides of the given isosceles right triangle.

From the given information if is clear that he ratio of equal side and hypotenuse is $x:x\sqrt{2}$ . So,

$\dfrac{x}{x\sqrt{2}}=\dfrac{l}{7\sqrt{2}}$

$\dfrac{1}{\sqrt{2}}=\dfrac{l}{7\sqrt{2}}$

$\dfrac{7\sqrt{2}}{\sqrt{2}}=l$

$7=l$

Therefore, the lengths of the other two sides of the given isosceles right triangle are 7 units.
