Answer and Explanation: Thus, the measure of central angle is as: CA=360∘n C A = 360 ∘ n . Thus the internal angle is product of central angle and difference of sides and 2, while external angle is equal to central angle.

By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc. The measure of the central angle ∠POR of the intercepted arc ⌢PR is 90°. Therefore, m∠PQR=12m∠POR =12(90°) =45°.

Vertical angles are always equal in measure. Vertical angles are congruent. Vertical angles, such as ∠1 and ∠2, form linear pairs with the same angle, ∠4, giving m∠1 + m∠4 = 180 and m∠2 + m∠4 = 180.

Acute. Draw a vertical line connecting the 2 rays of the angle. To determine the number of degrees in an acute angle, connect the 2 rays to form a triangle. Line up the short end of your ruler with the bottom ray, then draw a vertical line intersecting the other ray using the long side of your ruler.

The part of SOHCAHTOA that has both of these parts is SOH, or sin θ = opposite/hypotenuse. Use this to solve for the angle. You can check your work in Part B if you use the answer we got as the 'adjacent' side of the triangle. If you use the ladder as the hypotenuse, use CAH, or cos θ = adjacent / hypotenuse.

Determining Length or Width When You Know the Other The area of a rectangle (A) is related to the length (L) and width (W) of its sides by the following relationship: A = L ⋅ W. If you know the width, it's easy to find the length by rearranging this equation to get L = A ÷ W.
