Answer:

x = 5 units

Step-by-step explanation:

Use the Pythagorean Theorem:

a^2 + b^2 = c^2

Set Values for Variables:

Side Length - a = 12

Side Length - b = x

Hypotenuse - c = 13

* Hypotenuse is always opposite from the right angle.

Solve:

12^2 + b^2 = 13^2

144 + b^2 = 169

(Subtract 144 from both sides to get 25)

b^2 = 25

(Find square root of 25 and b^2)

b = 5

Conclude:

Now you know x (otherwise known as the b-value), is equal to 5 units.

Answer:

x = 5

Step-by-step explanation:

Just use the Pythagorean Triangle:

13^2 - 12^2 = x^2

x^2 = 25

x = 5

Which of the following equations has the same solution as m - (-62) = 45?

Alborosie

Well in the first equation m= -17
So you just have to substitute -17 in and see if it makes sense
like with the first equation -17 + 25 does equal 8 therefore x (in the second equation) = m (in the first)

Which of the following statements best describes the relationship between a line and a point in a plane? exactly one plane conta

Alexandra [31]

Answer: (b) exactly one plane contains a given line and a point not on the line.

Step-by-step explanation: The basic postulates of geometry are very-well known to all of us. For example-

(i) The intersection of two lines determines a point,

(ii) Two parallel lines give result to a plane,

(iii) A line and a point not on the line determines a plane, etc...

Thus, with the help of the third point, we can easily arrive at the conclusion that a given line and a point not lying on the line is contained in a plane. For example- see the attached figure, AB is a line and P is any point not on the line. They both contained in the plane ABC.

Hence, the correct option is (b).
