If the bottom side is 20 cm, then each line BE and CE would each be 10 cm.
Now, just focus on the top left triangle. You have one side with 20 cm, and the other side with 10 cm. You are left with the hypotenuse, which you need to figure out the value of.
Since this is a right triangle, you can use the Pythagorean theorem -> a^2 + b^2 = c^2 where c is the hypotenuse.
20^2 + 10^2 = c^2
400 + 100 = c^2
500 = c^2
22.36 = c
Answer:
Step-by-step explanation:
E is the midpoint of BC
So, BE = 20/2 = 10 cm
ΔABE is a right angled triangle. So, to find AE, we can use Pythagorean theorem.
hypotenuse² = base² + altitude²
AE² = BE² + AB²
= 10² + 20²
= 100 + 400
= 500
AE = √500
AE = 22.4cm

Ben is rock climbing in the Grand Canyon. He starts off 59.3 feet above sea level and descends into the canyon. The difference between his starting and ending elevation is 129.6 feet. What is Ben's final elevation?
Answers
Answer: -70.3 feet
Step-by-step explanation:
Let Ben's final elevation be represented by x.
We are informed that he starts off 59.3feet above sea level and descends into the canyon and that the difference between his starting and ending elevation is 129.6 feet. This will then be expressed in an equation as:
59.3 - x = 129.6
x = 59.3 - 129.6
x = -70.3
Therefore, the final elevation is -70.3 feet.
can someone help? This is for a final product.

y = [tex]\frac{5}{4} \\[/tex] x
Step-by-step explanation:
You need to find b to substitute m and b into the equation y = mx + b
So to solve for b substitute what you know -5 = [tex]\frac{5}{4} \\[/tex](-4) + b
So -5 = -5 + b, and b = 0 so put it all together y = [tex]\frac{5}{4} \\[/tex] x + 0 so y = [tex]\frac{5}{4} \\[/tex] x
11) Peyton is sitting on the ground at the park flying a kite. The length of the kite string is 50 feet and the kite is directly above a tree. Peyton is sitting 25 feet away from the tree. How high is the kite flying in the air? Round to the nearest tenth.
Answers
Answer: 43.30 ft
Step-by-step explanation:
Given
The length of the string is [tex]L=50\ ft[/tex]
Distance between Peyton and the tree is [tex]x=25\ ft[/tex]
Using the figure, apply Pythagoras theorem
[tex]\Rightarrow L^2=h^2+x^2\\\Rightarrow h^2=50^2-25^2\\\Rightarrow h=\sqrt{2500-625}=43.30\ ft[/tex]
The kite is flying 43.30 ft above the ground

We know it won’t be up or down because the 2 would have to be on the outside. It must be to the right because it will go the opposite of the sign in the parentheses (in this case -2). So instead of going left you’d go right!

Answer For The Problem 2x3 (Divide it by the numbers I give you meaning divide the number two by what I give yo and the other number 3 by it.
The common factors for 2,3 are −1,1 . The numbers do not contain any common variable factors. The GCF (HCF) of the numerical factors −1,1 is 1 .The number is one.
Answer For The Problem 2x5 is also 1 so decide both 2&5 by 1 then multiply. After doing that for answers 2&3 add them. last if you then subtract 22 that might be the answer so put that & also put the answer of the greatest common factor of 22 which is 3. Make sure to include that the one where you subtracted 3 was the greatest common factor for 22.

The Length of a rectangle is twice the with the area of the rectangle is 90 square units know that you can divide the rectangle into two squares which number represents the length of each side of the Squares
Answers
Answer:
2√45units
Step-by-step explanation:
Area of the rectangle = Length × Width
A = LW
If the Length of a rectangle is twice the width, then;
L = 2W
A = 2W(W)
Since area = 90
90 = 2W²
W² = 45
W = √45
Get the length
L =2W
L = 2√45 units
Hence the length of square is 2√45units
