WebJan 31, 2024 · To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4 Since √3 / 4 is approximately 0.433, we can formulate a quick recipe: to approximate the area of an equilateral triangle, square the side's length and then multiply by … WebAn obtuse triangle has only one obtuse angle – the other two angles are acute angles, with measures less than 90 degrees. The proof comes from the fact that the three angles in a triangle add up to 180 degrees. If two angles in a triangle were obtuse (greater than 90 degrees), their sum would already be more than 180 degrees. buffalo kids clothesWebThe correct option is A 25∘ Given: One of the angles of a triangle is 130∘. And the remaining two angles are equal. Let us assume that the second and third angle be x. We know that sum of all the angles of a triangle = 180∘ 130∘ + x + x = 180∘ 130∘ + 2x = 180∘ 2x = 180∘ – 130∘ 2x = 50∘ x = 50 2 x = 25∘ Therefore the two other angles are 25∘ each. buffalo kids westside gunn

"WebSupplementary angles add up to 180° - example: 50° & 130° are supplementary (added together, they form a straight line) Two facts: (1) 90° comes before 180° on the number line (2) "C" comes before "S" in the alphabet You can use this to help you remember! 90° goes with "C" for complementary so complementary angles add up to 90° " - If one angle of a triangle is 130 degree
