How do you find the base of right triangle when you have the height and the angle?
Let the angle = θ
Let the height = a
Let the base = b
* means multiplied by
If the angle touches the base:
tanθ = a/b
b = a/tanθ
If the angle touches the height:
tanθ = b/a
b = a*tanθ
When transferring the second line of working (b= ...) into a calculator, replace a with the height and θ with the angle. The answer will be b.

How do you find the height of a right triangle with only knowing its base and base angle?
You have to use trig. If the base angle is a and base b, the height is b tan(a).
In a right triangle the sides that for the right angle are called what?
The two sides are called base and height and the sloping part of the right angle triangle is called the hypotenuse.
Can height and base be equal of right triangle?
Yes and it will have a 90 degree angle and two angles of 45 degrees. Such a triangle is called an isosceles right angle triangle.

How do you find the are of a right triangle?
Area = 1/2 b h b : base h : height The height is vertical side of the right angle; the base is the horizontal side of the right angle
How do you calculate the height of right triangle given the base and adjacent angle?
Height will be h=base*tan(angle).
What area of right triangle?
Area of a right angle triangle is: 0.5*base*height
Can you work out the area of any triangle using bxh divided by 2?
Yes, that works for any triangle. The height always has to be at a right angle to the base. If there is an angle over 90 degrees, you may have to extend the base.Yes, that works for any triangle.

Area of a right angle triangle?
area=(1/2)*base*height

Area = 1/2 b h b : base h : height The height is vertical side of the right angle; the base is the horizontal side of the right angle
What is the height of the triangle?
The height of a triangle is the point from the base to the upmost point of the triangle. On a right triangle, it is measured on the the longest side that makes a right angle. Thanks for using Answers.com!
What do you have to do to the area of a right angled triangle?
The area of a triangle is one half base times height. In the case of a right triangle, the base is one leg and the height is the other leg. (The two legs being separated by the right angle.)
How do you calculate the base of the right triangle given the height and the opposite angle?
By using the tangent ratio of: opposite/tangent angle = adjacent which is the base
