WebSep 4, 2024 · By the Pythagorean theorem, x 2 = 3 2 + 6 2 = 9 + 36 = 45 and x = 45 = 9 5 = 3 5. By Theorem 7.3. 3, y = B P = A P = 6. Answer: x = 3 5, y = 6. Example 7.3. 4 Find x: Solution By Theorem 7.3. 3, A P = B P. So A B P is isosceles with ∠ P A B = ∠ P B A = 75 ∘. Therefore x ∘ = 90 ∘ − 75 ∘ = 15 ∘. Answer: x = 15.
