WebHint: The total degrees you must turn to draw any closed shape is 360 degrees. So all of your turns should add up to 360 degrees. Hopefully you found that an angle of 120 degrees at each turn is needed to draw a triangle, giving us a final script of: But you may have noticed you use the pattern three times. For a triangle this WebFor a spherical triangle, the sum of the angles is greater than 180° and can be up to 540°. Specifically, the sum of the angles is 180° × (1 + 4f), where f is the fraction of the sphere's … WebAnswer: At 2m, one steradian cuts through 2×2 = 4 m 2 of the sphere. And because the sensor is relatively small, its flat surface area is approximately the area of sphere that it occupies. So 0.05 × 0.05 = 0.0025m 2. So, one … gresham dublin hotel
