What is the value of a?
O5 units
O5 1/3 units
O6 2/3 units
O7 units

The value of a is  ⇒ 2nd answer

Step-by-step explanation:

Let as revise the Pythagoras Theorem

In the right triangle ABC, where ∠B is a right angle (AC is the hypotenuse, Ab and BC are the legs of the right angle)

(AC)² = (AB)² + (BC)²

(AB)² = (AC)² - (BC)²

(BC)² = (AC)² - (AB)²

If BD is drawn perpendicular to AC, we can use these rules

(AB)² = AD × AC

(BC)² = CD × AC

(BD)² = AD × CD

AB × BC = BD × AC

Step-by-step explanation:

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
