Answer:

LA theorem

Step-by-step explanation:

Consider right triangles AED and CED. In thes triangles:

  • m\angle AED=m\angle CDE=90^{\circ} - given;
  • m\angle EAD=m\angle ECD - given;
  • ED\cong ED by reflexive property.

So,

\triangle AED\cong CDE by LA theorem.

LA theorem states that if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent

Melanies blue notebook cover is 20 centimeters by 30 centimeters. She has a sticker for each letter in her name. Each sticker is
gizmo_the_mogwai [7]
Find the surface area of her notebook.

30 + 30 + 20 + 20 = 100

Now find the surface area of the square stickers.

2 + 2 + 2 + 2 = 8

So this is the surface area of one square, now multiply it by 8.

8 * 7 = 56

This is the surface area of all the stickers, now subtract it to the surface area of the notebook:

100 - 56 = 44

So 44 centimeters of the notebook cover will still be showing.

What is the value of x2+9x+20 when x could be -5, -3 or -6
ANTONII [103]

Answer:

Step-by-step explanation:

You should use a ^ to indicate an exponent. x^2 is the same as x².

x² + 9x + 20

Replace the x with (-5).

(-5)² + 9(-5) + 20 = 25-45+20 = 0

Then do the same with x = (-3):

(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2

You can do x = (-6)

How do i plot 2 3/10 on a number line ?
klemol [59]

Answer:

First, find 2. Then find the 3/10 mark following 2 (if there is one). That is where you put your point. If there are no 10ths markings, it is up to you or your teacher how to plot it.
