## What is the sine formula for area?

You have the lengths of two sides and the measure of the included angle. So, you can use the formula R=12prsin(Q) where p and r are the lengths of the sides opposite to the vertices P and R respectively. Using the formula the area, R=12(3)(4)sin(145°) .

### How do you find the area of a triangle with SSA?

The formula to calculate the area of a triangle using SAS is given as,

1. When sides ‘b’ and ‘c’ and included angle A is known, the area of the triangle is: 1/2 × bc × sin(A)
2. When sides ‘b’ and ‘a’ and included angle B is known, the area of the triangle is: 1/2 × ab × sin(C)

How can I get SSS area?

The most common formula for finding the area of a triangle is K = ½ bh, where K is the area of the triangle, b is the base of the triangle, and h is the height.

How do you find the area of a triangle with SAA?

To calculate the area of a triangle given one side and two angles, solve for another side using the Law of Sines, then find the area with the formula: area = 1/2 × ​b​ × ​c​ × sin(A).

## Is AAA congruence possible?

It is not justified because AAA is not a congruence criterion. Triangles with similar measures of angles can be similar triangles but not congruent. Two similar triangles can also have all equal angles but different lengths of sides, so one triangle could be an enlarged version of another triangle.

### How do you find area with different lengths?

How to use irregular area calculator?

1. Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).
2. Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2.
3. Step 3: Press calculate button.
4. Our Formula: Area = b × h.

What is the maximum value of sin, cos, and Tan?

The graphs of sinx, cosx and tanx Sine • The maximum value of sinx is 1. At x = 90°, sinx = 1. • The minimum value of sinx is −1. At x = 270°, sinx = −1. • The graph of sinx crosses the x-axis three times in the interval 0° ≤ x ≤ 360°. At x = 0°, 180°, and 360°, sinx = 0. • The graph of sinx is the same shape as the graph of cosx, but it is

Why is tan equal to Sin divided by cos?

sin θ = Opposite Side/Hypotenuse.

• sec θ = Hypotenuse/Adjacent Side.
• cos θ = Adjacent Side/Hypotenuse.
• tan θ = Opposite Side/Adjacent Side.
• cosec θ = Hypotenuse/Opposite Side.
• cot θ = Adjacent Side/Opposite Side.
• ## How to calculate sin, cos, tan on a calculator?

First divide the numbers 0,1,2,3,and 4 by 4 and then take the positive roots of all those numbers.

• Hence,we get the values for sine ratios,i.e.,,½,1/√2,√3/2,and 1 for angles 0°,30°,45°,60° and 90°
• Now,write the values of sine degrees in reverse order to get the values of cosine for the same angles.
• ### What does sin, cos, and Tan mean in calculus?

cos refers to the cosine function. sin refers to the sine function. tan refers to the tangent function. To begin, these are trigonometric functions. Each relates an angle, , to the sides of a right triangle. Many trigonometry students use the phrase, SOHCAHTOA (say “so-ka-toe-uh”) to keep it straight. log refers to the logarithm function.
