A2 + B2 = C2:
13 squared plus b2 equals 18 squared. What is the answer? Please show the work.

Solving we get

Step-by-step explanation:

13 squared plus b2 equals 18 squared. What is the answer?

We can write it as:

Now, solving and find value of b

We know that 13² = 169

and 18² = 324

Putting values:

Subtract 169 on both sides

Now, taking square root on both sides

So, solving we get

table a is wierd

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
