Answer:

  • The value of x is 12 units.

Step-by-step explanation:

<u>We know that:</u>

  • Formula: h² = a² + b²

<u>Let's solve using Pythagoras theorem.</u>

  • => 13² = 5² + x²
  • => 169 = 25 + x²
  • => 169 - 25 = x²
  • => 144 = x²
  • => √x² = √144
  • => x = √144
  • => x = 12

Hence, the value of x is 12 units.

Two legs of a right triangle are 4cm, and 3cm. find the length of the hypotenuse of this triangle
sergiy2304 [10]
It'll be 4^2+ 3^2 then the answer you get you take the square root of it which will give you the hypotenuse.
Your answer would be 5 because square root of 25 is 5
If u want the formula it's a^2+b^=c^2
C is the hypotenuse and a and b is the lengths

Hannah is 2 times her sister’s age. The sum of their ages is no more than 18 years. 1) Write an inequality that can be used to r
svetoff [14.1K]

Answer:

1) x+2x\leq 18.

2) 6 years

Step-by-step explanation:

Let Hanna's sister be x years old.


Then Hanna will be 2x years old.


The sum of their ages will be x+2x years.

The statement "no more than 18" means the sum of their ages is less than or equal to 18.

The required inequality is;

x+2x\leq 18.

2)

The inequality we just found is


x+2x\leq18.

We simplify to get;

3x\leq 18.

we divide both sides by 3 to get;

x\leq 6.

Therefore the oldest age Hannah's sister can be is 6 years

look at the figure shown below which step should be used to prove that point a is equidistant from points c and b
JulijaS [17]
D
is certainly wrong. You could extend the length of AD as far as you want and the two triangles (ABD and ACD) would still be congruent.

C
is wrong as well. The triangles might be similar, but they are more. They are congruent.

B
You don't have to prove that. It is given on the way the diagram is marked.

A
A is your answer. The two triangles are congruent by SAS
