# Can you solve a right triangle with one side and one angle?

## Can you solve a right triangle with one side and one angle?

How do you solve a right angle triangle with only one side? If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle.

How do you solve a triangle if you know one angle?

Use the sine rule if given only one angle and two lengths of a triangle. The formula is sin A/a = sin B/b, where “A” and “B” are angles and “a” and “b” are the lengths of the sides opposite these angles, respectively.

### How do you use CAH?

The hypotenuse is always opposite the right angle. The sine of an angle is equal to the side opposite the angle divided by the hypotenuse….Sohcahtoa Calculator.

How do you find one side of a right triangle?

Right Triangles and the Pythagorean Theorem

1. The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
2. The side opposite the right angle is called the hypotenuse (side c in the figure).

#### How do you find the sides of a right triangle?

What is the third side of a right triangle?

hypotenuse
The third side is the hypotenuse, which is 20√2m . This is an example of an iscoseles right triangle, in which the angles are 45-45-90 degrees. In an iscoseles right triangle, the base and height are the same.

## What is Sohcahtoa called?

“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2)

What is Sohcahtoa used for?

SOHCAHTOA is a mnemonic device helpful for remembering what ratio goes with which function. With these properties, you can solve almost any problem related to finding either a side length or angle measure of a right triangle. SohCahToa can ensure that you won’t get them wrong.

### What is the measure of one angle in a triangle?

In a triangle, one angle is 70 degrees and the other two angles are such that the one which is lesser is measured by 20 degree than the other. What are the measures of these two angles?

How many angles does a right triangle have?

A right triangle is a type of triangle that has one angle that measures 90°. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry.

#### What is the definition of a right triangle?

A right triangle is a type of triangle that has one angle that measures 90°. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse.

What is the sum of all 3 angles of a triangle?

The sum of the angles of a triangle is 180˚. The second angle of a triangle is 44 degrees more than the first angle and the third angle is 28 degrees less than twice the second angle. What is the measure of all three angles? Let 1st angle of a triangle = x°, then 2nd angle = (x+44)°. or. 4x°+104°=180°. or. x= 76°/4 =19°.
