WebThe measure of each interior angle of a regular polygon is 160 . How many sides does the polygon have? (a) 22 (b) 20 (c) 18 (d) 16 (e) 24 6. A cube has surface area of 36 square … WebDec 24, 2011 · Study now. See answer (1) Best Answer. Copy. Equilateral. * * * * *. Not necessarily. A triangle with angle measuring 50, 60 and 70 degrees is a triangle with three acute angles but it is certainly not equilateral. Wiki User.
1.2: Trigonometric Functions of an Acute Angle
WebAll three angles in any triangle always add up to 180 degrees. So if you only have two of the angles with you, just add them together, and then subtract the sum from 180. A Triangle has three angles A, B, and C. Angle A equals 60, Angle B equals 84. Triangle exterior angle example. Worked example: Triangle angles (intersecting … So over here, we have one angle that's 92, one angle that's 29. The other one will … This is because a straight angle equals 180, adding the two must equal 180. So we … WebAn angle is obtuse when it measures greater than 90 degrees. Exterior angles are obtuse if they are adjacent to an acute interior angle. On the other hand, if they are adjacent to an obtuse interior angle, then the exterior angle is acute. Hence, no … graham nash songs for beginners cd
What Is an Acute Triangle? - Study.com
WebTherefore, the unknown angle can be calculated using the formula. Sum of interior angles of a triangle = Angle 1 + Angle 2 + Angle 3. ⇒ 180° = 45° + 63° + Angle 3. ⇒ Angle 3 = 180° - (45° + 63°) Angle 3 ⇒ 72°. ∴ The … WebAn acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse … WebThe right triangle: The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... y + z = 90 degrees. The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse. graham nash songs for survivors
