Correct answer Explanation We know that in a 3060=90 triangle, the smallest side corresponds to the side opposite the 30 degree angle Additionally, we know that the hypotenuse is 2 times the value of the smallest side, so in this case, that is 10 The formula for Since a triangle is a right triangle, the Pythagoras formula a 2 b 2 = c 2, where a = longer side, b = shorter side, and c = hypotenuse is also applicableFor example, the hypotenuse can be obtained when the two other sides are known as shown below Use the and triangle relationships to solve for the missing sides Use the answers to reveal the name of the team that Abraham M Saperstein established and sent on the road in 1927 600 300 450 450 600 600 450 450 600 60 12 300 600 450 300 45 16 300 450 3a la 5b 8b 8a 1b 5a 4a 4a 1b 2a 2b 9b 8a 5b 7b 4b 3b 6a 4b

About Triangle A triangle is a unique right triangle whose angles are 30º, 60º, and 90º The triangle is unique because its side sizes are always in the proportion of 1 √ 32 Any triangle of the kind can be fixed without applying longstep approaches such as the Pythagorean Theorem and trigonometric featuresCheck out this tutorial toA triangle is a special right triangle that contains internal angles of 30, 60, and 90 degrees Once we identify a triangle to be a 30 60 90 triangle, the values of all angles and sides can be quickly identified Imagine cutting an equilateral triangle vertically, right down the middle Each half has now become a 30 60 90 triangle
What is the Triangle rule? A triangle is a unique right triangle that contains interior angles of 30, 60, and also 90 degrees When we identify a triangular to be a 30 60 90 triangular, the values of all angles and also sides can be swiftly determined Imagine reducing an equilateral triangle vertically, right down the middle Triangle is a special kind of triangle The sides of degree triangles have a unique ratio For instance, the two legs are the same length, and the hypotenuse equals that length times the square root of 2
