Use the Pythagorean theorem to find the value of b²

So what is the Pythagorean Theorem:

  ⇒ it states the sum of both leg's lengths squared is equal to

      ⇒  hypotenuse's length squared

  (look at the image attached for a better explanation)

To find out , let's look to the Pythagorean equation to see what we are missing:

So b^2 = 225 ⇒ Choice B

Hope that helps!

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3
