The pythagorean theorem is true for some right triangles, but not all. a. true b. false

The given statement is  a FALSE statement.

Pythagorean Theorem--

It states that if a and b are two legs of a right angled triangle and c is the hypotenuse of the right angled triangle then,

The square of hypotenuse is equal to the sum of the square of the two legs of the triangle.

i.e.

This theorem is true for all the right triangle.

Option: B is the correct answer.

          B.False

care to share were the trapezoid shown is ?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
