, find the triangle's smallest height. A.6 B.12 C.12.5 D.13 E.15相关知识点: 试题来源: 解析 B This is a Pythagorean triple (a 3−4−5 actually) with legs 15 and 20. The area is then (15)(20)2=150. Now, consider an altitude drawn to any side. Since the area remains ...
A Let x be the length of the first side. The lengths of the sides are: x, 3x, and 15. By the Triangle Inequality, 3x<x+15, 2x<15, x<152. The largest integer satisfing this inequality is 7. So the largest perimeter is 7+3⋅7+15=43⇒A.反馈...

What is a triangle with 3 acute angles? Can an equiangular triangle be scalene? A triangle has side lengths of 6, 8, and 9. What type of triangle is it? What is the length of the third side of this triangle? What are the sides of a right triangle?
On the other hand, anisosceles triangleis a triangle withtwo sides of equal length. If a triangle hasall sides with different lengths, it is said to be ascalene triangle. Based on Interior Angles Triangles can also be classified based on the measure of their interior angles. There are three...
