Two sides of the triangle are identical
A triangle is 180 degrees
180-40 is 140
and then 140 divided by two is 70 (since the two angles that were remaining were identical due to the sides being identical)
I hope this helps!

Find the midpoint of the line segment joining the two points.<br> (1.8, -3.4) and (-0.4, 1.4)
murzikaleks [220]

Answer:

(0.7, -1)

Step-by-step explanation:

To find the coordinates for the midpoint you add each coordinate together and divide by 2.

M = (\frac{1.8 - 0.4}{2},  \frac{-3.4 + 1.4}{2})

M = (\frac{1.4}{2}, \frac{-2}{2})

M = (0.7, -1)

A tarp is used to keep the infield of a baseball field from getting wet. The infield is a square. The corners of the square tarp
Dafna11 [192]

Answer:

<h2>a. 2,025 ft</h2><h2>b. 8,100 is a perfect square. </h2>

Step-by-step & explanation:

<em>It is a perfect square because if it wasn't, it wouldn't be equally a whole number when divided by 4 or 2,025 exactly on ALL 4 sides and when finding the root of 8,100 it's a perfect 90.  As you should already know a perfect square has a given 90 degree angle.</em>

Tarp = 8,100 sq ft.

- anchored corners at the base.

- Square infield.

Well if there's 4 bases, divide 8,100 by 4.

8,100 / 4 = 2,025

One base to another base is 2,025 ft.
