False.

The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.

It also equals 13 12.

I suggest that it is (sin A)^2 + (cos A)^2 = 1

Just remember SOHCAHTOA,

SOH is using the sine, only use this when you have the Hypotenuse and the Opposite.

Sin(a)= O/H

CAH is using the cosine, only use this when you have the Hypotenuse and Adjasent.

Cos(a)=A/H

TOA is using the tangent, only use this when you have the Opposite and Adjasent.

Tan(a)=O/A

Tangent is used in calculus to compute the slope of a curve. Because curves do not have uniform slopes, unlike lines, their slopes change. A tangent is the slope of a curve at a specific point.

The corresponding angles in both cases are the same. With congruent triangles, the lengths of the corresponding sides are also equal.

180/10 = 18 square meters of cross-sectional area.

Since the prism is a triangle, that means that the height x width = 36, since A = (H*W)/2

Therefore you could say 6x6, 18x2, 4x9, or even 36x1.

You find the angle with a fixed direction using trigonometry. You then convert it to an angle measured in degrees, clockwise from North, and written as a three digit number.

At the bottom, the car has kinetic energy of ½mv2. At the top, the car has kinetic energy of 0. If we ignore friction and wind resistance, the initial kinetic energy is converted to gravitational potential energy of mgh, where the m is again the mass of the car, g is the acceleration of gravity, and h is the vertical change in position of the car. Solving the two equations for h, we get

h=½v2/g=(0.5)(25 m/s)2/(9.8 m/s2)=31.888 m

To find the distance traveled along the road, we use a bit of trigonometry: sin(30°) = h/d = 0.5, so d = 2h = 63.776 meters

Of course, the actual value will be less, due to the friction and wind resistance that we ignored in our calculations.

The answer depends on the context. The applications will vary from one context to another.

There are agricultural fields.

There are vector fields in physics which depict the magnitudes and directions of forces.

There are algebraic structures called fields which have some mathematical properties associated with them.

If y=xm2+76l-k+sl3474?

The specific location of something or in which something is occurring or has happened, or the measurement of something that happened or is happening is a point in geometry.

There can be no equivalence.

A mil is a measure of length or linear displacement while a revolution is a measure of angular displacement. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

you use math in everyday of your life !

0.4Y+5=1

Not specifically trigonometry, but functions in general. As a general rule, functions must be evaluated before using the results in other parts of the calcuation.

The identity for tan(theta) is sin(theta)/cos(theta).

12 feet.

An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.

Y= 6/7x +6

The angles of a triangle sum to pi radians, or the angles at a point sum to 2*pi radians.

there can be more than 1 answer for some trig equations and you must use your knowledge of periodicity to get the answers.

It is not clear from the question where the point A is. This answer assumes that A is the point to the East of the hill.

Suppose the height of the hill is h metres. Suppose O is the point, on ground level, under the apex of the hill.

Then tan(39) = h/OA so that OA = h/tan(39)

Also tan(27) = h/OB so that OB = h/tan(27)

Now, triangle OAB has a right angle at A,

so by Pythagoras, OB2 = OA2 + AB2

Therefore h2/tan2(27) = h2/tan2(39) + 5002

that is h2/0.2596 = h2/0.6558 + 250000

so that 2.3269h2 = 250000

h2 = 107441

h = 327.8 metres.

No, it is not. To be correct, the expression requires parenthesis, which are missing.
