Which triangle can be solved using the law of sines?

The Law of Sines can be used to solve oblique triangles, which are non-right triangles. According to the Law of Sines, the ratio of the measurement of one of the angles to the length of its opposite side equals the other two ratios of angle measure to opposite side. There are three possible cases: ASA, AAS, SSA.

Under what condition does y1 y2 y3 Do points?

10. Under what condition on y1, y2, y3 do the points (0,y1), (1,y2), (2,y3) lie on a straight line? Solution: The points (0,y1), (1,y2), and (2,y3) will lie on the same line if and only if the slope of the line segment from (0,y1) to (1,y2) is the same as the slope of the line segment from (1,y2) to (2,y3).

For which triples y1 y2 y3 Does the system Ax y have a solution?

For which triples (y1,y2,y3) does AX = Y have a solution? (y1 – 8y2 – 5y3)   . Therefore, a general solution to this system is given by (x1,x2,x3)=(- 1 2 (y1 -2y2 -y3),- 1 6 (y1 -2y2 +y3), 1 6 (y1 -8y2 -5y3)) .

How to find the formula for trigonometry angles?

The formulas for trigonometry angles are based on the four quadrants of a unit circle. See the figure below to understand. Question 1: Find the value of sin 60 – cos 30. Question 3: If sin 3A = cos (A-26°), where 3A is an acute angle, find the value of A. Given that, sin 3A = cos (A-26°) ….

How to find Sin 480° using trigonometric ratios?

If the given angle measures more than 360 degree, we have to divide it by 360 and write the remainder in one of the above forms. If we write the given angles in the form (90 + θ), (90 – θ), (270 + θ) or (270 – θ), we have to convert the given trigonometric ratios as follows. We have a advantage for cos and sec functions. Find the value of sin 480°.

How do you find the trigonometric ratio of 549 degrees?

To determine the basic trigonometric ratio of such angle, we subtract a suitable positive multiple of 360° till the angle is positive and less than 360°. Thereafter, we apply the appropriate procedure to determine its trigonometric ratio in question. Find the cosine of 549°. cos 549° = cos (549° – 360°) = cos189°

What is the trigonometric ratio of an angle more than 360 degrees?

Trigonometric ratios of angles more than 360°. An angle that is more than 360° implies that an object underwent a rotation that is more than one cycle about a fixed point. To determine the basic trigonometric ratio of such angle, we subtract a suitable positive multiple of 360° till the angle is positive and less than 360°.
