and the side opposite to the smallest angle will be the smallest. Similarly, the angles opposite to the sides will be in the same order as identified in step 1. Thus, the angle opposite to the greatest side will be the largest and the angle opposite to the smallest s...
To find the angles of a triangle whose interior and exterior angles are in the ratio of 2:7, and where the other two interior angles are in the ratio of 3:4, we can follow these steps:Step 1: Define the angles based on the given ratios.

Special Angles: 30 and 60 Let us first consider 30˚ and 60˚. These two angles form a 30˚-60˚-90˚ right triangle as shown. The ratio of the sides of the triangle is 1:√3:2 From the triangle we get the ratios as follows: ...
Frequently Asked Questions How can you identify alternate exterior angles? Alternate exterior angles are the angles that lie outside of the pair of lines they were formed from and are opposite each other. They lie on opposite sides of the transverse line that crosses the pair of lines. They...
Suppose if one angle is x then the other angle will be 90°– x. Hence, we use thesecomplementary angles for trigonometry ratios, where one ratio is complementary to another ratio by 90 degrees such as; sin (90° – A) = cos A and cos (90° – A) = sin A ...
Trigonometric formulas play a crucial role in solving trigonometry problems. Likewise, the sine, cosine, the other remaining ratios, and the tangent ratio have some unique and interesting formulas. A few trigonometric formulas of the tangent ratio are {eq}\tan \...
Cosine ratios are exactly the same idea of sine ratios or tangent ratios. The only difference between it and the other two trigonometric ratios is that it is the ratio of the adjacent side to the hypotenuse of a right triangle. Trigonometric ratios cosine rule The cosine rule tells us tha...
