在这个部分,一定要注意,角度和对应的边是匹配的,不然是计算不出正确答案的。 3、Area of a triangle 这个公式适用于任意三角形,也就是说无论是钝角,直角等边等腰或是一个不规则三角形,我们都可以使用。使用的前提是我们要已知这个三角形内的两条边以及这两条边所形成的夹角。 这道题目呢是利用我们公式的反向运...

Using Sine to Find the Area of a Triangle from Chapter 14/ Lesson 9 17K A trigonometric formula that uses two sides of the triangle and the adjacent angle, along with the sine function on your calculator, can determine the area of that triangle when the height is unknown. This lesson deta...
Sine, cosine, and tangent can be used to solve for missing sides if at least one side and one acute angle in a right triangle are known. The function used is determined by the information given. Sine is the ratio of the opposite side over the hypotenuse, cosine is the ratio of the ad...
