Customer Voice. Questionnaire. FAQ. Webdegrees Correct answer: degrees Explanation: The interior angles of a triangle always add up to 180 degrees. We are given angle and since this is indicated to be a right triangle we know angle is equal to 90 degrees. Thus we know 2 of the 3 and can determine the third angle. Angle is equal to 55 degrees.

WebA degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees.. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 π … WebJun 19, 2015 · A right angle has 90 degrees. The question is how many degrees does a right triangle have? All triangles have a total of 180 degrees, no matter how the degrees are split between the angles. Remember: a quadrilateral has 360 degrees, and a triangle, no matter what type, is half of a quadrilateral. 360 cut in half, or divided by two, is 180, no … dogfish tackle \u0026 marine

WebNov 9, 2024 · When the rays form exactly an angle measuring 90˚, it is known as a right angle. Note: Angles are measured in degrees with the symbol ‘ ˚ ’ or in radians with the abbreviation ‘rad’. In radians, the measure of a right angle is π/2. This is because in the radian metric system, the value of π = 180˚. Therefore 180˚/2 or π/2 = 90˚. WebAngles are measured in degrees. The five main types of angles are: Acute: An angle between 0 and 90 degrees. Right: A 90-degree angle. Obtuse: An angle between 90 and 180 degrees. Straight: A 180-degree angle … WebJul 12, 2024 · Since we can find coterminal angles by adding or subtracting a full rotation of 360 degrees, we can find a positive coterminal angle here by adding 360 degrees: − 45 ∘ + 360 ∘ = 315 ∘.
