Can you take the exact value of 130?

Can you take the exact value of 130?

Since 130 is not a perfect square, it is an irrational number. This means that the answer to “the square root of 130?” will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

What is sin120?

The sin 120-degrees value can be identified using either unit circle or with the help of other trigonometric angles such as 60, 180 degrees and so on. It means that, sin 60 = sin 120 = √3/2.

What is the value of sin 120 in fraction?

Solution: sin 120° = sin(180° − 120°) = √3/2.

What degree is straight angle?

180 degrees

How do you identify a 90 degree angle?

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

What is the name of 90 degree angle?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

What do you call a 0 degree angle?

An angle with a measure of zero degrees is called a zero angle.

Which angle is larger than straight?

Angles larger than a straight angle but less than 1 turn (between 180° and 360°) are called reflex angles. An angle equal to 1 turn (360° or 2π radians) is called a full angle, complete angle, round angle or a perigon.

What does 180 angle look like?

A 180 degree looks like a straight line.

What type of angle is 105?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees. straight angle-a 180 degree angle.

How do you know if its a right angle?

When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle. A right angle is represented by the symbol ∟.

How many degrees is an angle?

360 degrees
