Does sin cos tan only work with right triangles

1 answer:

6 0

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.

I would say that they didnt because if you plug anythin in that equation it wont be a solution......i think thats what it meant

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

The value of a painting recently sold at an auction is expected to increase in value over time. The function v(t)=12,000(1.15)^t

tensa zangetsu [6.8K]

This is an exponential equation with a starting value of 12000 and an increase of 15% each years.

The following are true:

C. Each year, it increases by 15%

E. The painting's value was 12,000 at the time is was sold.
