Calculates formula for Triangles, Circles and more Home Geometry Geometry Calc Online Geometry Calculator Geometry Calc Gifs Algebra Solver Please pick a calculator. There are two ways to determine the measure of inscribed angles. Math Algebra Find the measure of the indicated angle to the nearest degree. A: Explanation of the answer is as follows Q: Find the measure of angle A to the nearest degree. Expert Answer 1st step All steps Final answer Step 1/3 Solution) According to the given figure ∠ A C B + ∠ B C D = 180 ° (Linear pair) ∠ A C B + 146 ° = 180 ° ∠ A C B = 180 ° − 146 ° = 34 ° View the full answer Step 2/3 Step 3/3 Final answer Transcribed image text: Determine the measure of each indicated angle. 7 Find the measure of the indicated angle to the nearest degree. Find the Indicated Angles | Midsegments The midsegment joins the midpoints of the nonparallel sides. Using the angle-sum property of a triangle and angles properties in trapezoids, find the measure of the indicated angle (s). 1) 65 72 97? 2) 72 65 97? 3) 48 20 52? 4) 72 54 90? 5) 64 48 80? 6) 56 42 70? 7) 12 16 20? 8) 16 65 63. 97030552 Now that I know that p = 11 (rounded to the nearest whole number), I can find the measure of angle m: 11/18 = sin (m°) sin −1 (11/18) = m° = 37. Q: Find the measure of the indicated angle to the nearest degree. Find the measure of the arc or angle indicated. Given the sizes of 2 angles of a triangle you can calculate the size of the third angle. So angle PRS is the angle with the pointy part at R and one side goes to P and the other to S, kind of like the middle letter is an elbow. Find the measure of the angles A and B. Answer: Step-by-step explanation: To find the angle they're talking about, angles are always named with the pointy part in the middle.
