Given circle E with diameter CD and radius EA. AB is tangent to Eat A.
faust18 [17]

The hypotenuse is equal to the square of the other two sides. The length of AC from the diagram is 21.9feet

<h3>Application of pythagoras theorem</h3>

The theorem states that the square of the hypotenuse is equal to the square of the other two sides

Given the following

Hypotenuse = 26 feet = CD
Base side = AD = 14ft

Required

Length AC

Use the theorem

26^2 = 14^2 + AC^2

AC^2 =  676 - 196
AC^2 = 480
AC = 21.9feet

Hence the length of AC from the diagram is 21.9feet

Can someone help me out
vichka [17]

Answer: LAST OPTION.

Step-by-step explanation:

The Pythagorean Theorem states the following relationship between the three sides of a triangle that has an angle of 90 degrees, known as "Right triangle":

a^2=b^2+c^2

Where "a"is the hypotenuse and "b" and "c" are the legs of the right triangle.

If the triangle ABC is a right triangle then AB must be equal to BC^2+AC^2, then, you need to substitute the values into  a^2=b^2+c^2 to check this:

12^2=5^2+10^2\\144\neq 125

Then the triangle ABC is not a right triangle.

Therefore, the statement that justifies why this triangle is not a right triangle is:

5^2+10^2\neq 12^2
