In a triangle abc right angled at b

To solve this problem, we need to find the values of the trigonometric functions for angle A in the right triangle ABC. First, let's label the sides of the triangle ABC.

Trigonometry is a branch of mathematics that gives the relationships between side lengths and angles of triangles. All trigonometric angles have fixed values and they can also be defined by the ratio of the lengths of the sides in a right-angled triangle. The six trigonometric as mentioned above are Sine, cosine, tangent, cotangent, cosecant, and secant. For a right-angled triangle, there is two way to obtain the relationship among all the sides of the triangle. The trigonometric ratios provide the ratio of two of the sides of the triangle, and the Pythagoras theorem provides the relationship among all the sides.

Sign in Open App. Correct answer is option 'A'. Can you explain this answer? Verified Answer. Most Upvoted Answer. To find: AC. We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse the side opposite the right angle is equal to the sum of the squares of the other two sides.

A triangle is a closed, two-dimensional shape that has 3 sides, 3 angles, and 3 vertices. It is the polygon with the fewest sides. Since it is the simplest form of a polygon, any polygon can be constructed using two or more triangles. One way that triangles are named is by labeling their vertices using either lower case or upper case letters, as shown in the figure below:. In the triangle above, the lower case letters are the sides and the upper case letters are their opposing angles. Referencing the above triangles, an interior angle is formed at each vertex of a triangle. These angles share the same name as their vertices. The measure of a triangle's sides and angles relative to each other can be indicated using tally marks and arcs. Refer to the figure below:.

In a triangle abc right angled at b

In Triangle ABC with the right angle at C , let a , b , and c be the opposite, the adjacent, and the hypotenuse of angle A. Then, we have. Let the other two angles be x and y which will be acute. Right triangles are a special case of triangles. You always know at least one angle, the right angle, and depending on what else you know, you can solve the rest of the triangle with fairly simple formulas. If you know any one side and one angle, or any two sides, you can use the pneumonic soh-cah-toa to remember which trig function to use to solve for others. Opposite refers to the side which is not part of the angle, adjacent refers to the side that is part of the angle, and the hypotenuse is the side opposite the right angle, which is C in the image above. For example,lets say you know the length of a and the value of angle A in the above triangle. Using the cosine function you can solve for c , the hypotenuse.
