Answer: 10mm

Step-by-step explanation: First you have to set up an equation using the formula: (a squared)+(b squared)=(c squared), (24 squared) + (x squared)=(26 squared

Then, solve for x: (26 squared)- (24 squared)= 676-576=100

Lastly, find the square root of 100, which is 10!

Hope this helps and I would appreciate it if you marked me as brainliest, but u don't have to!

a2+b2=c2

a=x

b=24

c=26

a2+24 squared=26 squared

a2+576=676

-576 -576

a2=100

Then, square root both sides.

It should be a/x=10

lesantik [10]

Answer:

False

Step-by-step explanation:

It is given that Noah thinks :

9x - 2x + 4x = 3x   as the subtraction sign after 9x tells us to subtract everything that comes after 9x.

This is wrong as according to the BODMAS rule, we have to do the addition operation first and then followed by subtraction operation.

That is

⇒ 9x - 2x + 4x

⇒ (9x -2x)+ 4x

⇒ 7x + 4x

⇒ 11x

Therefore the answer to the equation is 11x and not 3x.

hichkok12 [17]

This question is incomplete.

Complete Question

A twelve-foot ladder is leaning against a wall. If the ladder reaches eight ft high on the wall, what is the angle the ladder forms with the ground to the nearest degree?*

Answer:

42°

Step-by-step explanation:

From the question, the diagram that is formed is a right angle triangle.

To solve for this, we would be using the trigonometric function of Sine.

sin θ = Opposite side/ Hypotenuse

From the question, we are told that:

12 foot ladder is leaning against a wall = Hypotenuse

The ladder reaches 8ft high on the wall = Opposite side.

Hence,

sin θ = 8ft/12ft

θ = arc sin (8ft/12ft)

= 41.810314896

Approximately to the nearest degree

θ = 42°

Therefore, the angle the ladder forms with the ground to the nearest degree is 42°
