Does sin cos tan only work with right triangles

Mathematics

Trigonometric functions aren't to do with triangles specifically, they are to do with angles.

So no, they aren't only for right angled triangles.

For example, the formula (1/2)ab * sin(c) calculates the area of a triangle, and will work on isosceles and scalene triangles.

What is an equation of the line that passes through the point
Keith_Richards [23]

Answer:

5x - 4y = 32

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

5x - 4y = 36 ( subtract 5x from both sides )

- 4y = - 5x + 36 ( divide all terms by - 4 )

y = \frac{5}{4} x - 9 ← in slope- intercept form

with slope m = \frac{5}{4}

Parallel lines have equal slopes, thus

y = \frac{5}{4} x + c ← is the partial equation

To find c substitute (8, 2) into the partial equation

2 = 10 + c ⇒ c = 2 - 10 = - 8

y = \frac{5}{4} x - 8 ← in slope- intercept form

Multiply through by 4

4y = 5x - 32 ( subtract 4y from both sides )

0 = 5x - 4y - 32 ( add 32 to both sides )

32 = 5x - 4y, that is

5x - 4y = 32 ← in standard form
