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. WebIn additional to common angle relations theorems, the questions will also ask us to use two important circle-related facts. The first we've already covered in the previous section: the sum of central angle measures in a circle is 36 0 ∘ 360^\circ 3 6 0 ∘ 360, degrees . WebGiven a circle and an arc on the circle, the chord is the line that subtends the arc. A chord's perpendicular bisector passes through the center of the circle and bisects the angle. One half of the bisected chord is the sine of one half the bisected angle, that is, [12] and consequently the sine function is also known as the half-chord. earthrenew aktie
