WebMar 29, 2024 · To find the arc length with a sector area, multiply the sector area by 2. Then, divide the product by the radius squared ( (SA*2)/r^2). Your answer gives you the central angle in radians. You now have the central angle in radians, so simply multiply the central angle by the radius to find the arc length. Thanks! We're glad this was helpful. WebFeb 24, 2024 · Use side length c to find the perimeter of the triangle. Recall that Perimeter P = a + b + c, so all you need to do is add the length you just calculated for side c to the …

WebExample: Find lengths a and b of Triangle S. Step 1: Find the ratio. We know all the sides in Triangle R, and We know the side 6.4 in Triangle S. The 6.4 faces the angle marked with two arcs as does the side of length 8 in triangle R.. So we can match 6.4 with 8, and so the ratio of sides in triangle S to triangle R is:. 6.4 to 8 WebNov 18, 2024 · If not, it is impossible: If you have the hypotenuse, multiply it by sin (θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos … WebYou can ONLY use the Pythagorean Theorem when dealing with a right triangle.
