What is the formula for finding area of a rectangle?

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

How do you express the area of a triangle as a function of x?

Area = 1/2*base*height or A = 1/2*b*h. One vertex is fixed at the origin, at (0,0). The second is at (0,y), and the third at (x,y) which lies on the curve y=x^3. Therefore, we can rewrite point 3 as (x,y)=(x,x^3).

What is the function for the area of an equilateral triangle?

In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.

What is a right angle tool?

Square, in measurement, device consisting of two straightedges set at right angles to each other. It is used by carpenters and machinists for checking the correctness of right angles, as a guide when drawing lines on materials before cutting, or for locating holes. The tools shown in the Figure are carpenter’s squares.

How large is an obtuse angle?

An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees.

What is the biggest obtuse angle?

As the Angle Increases, the Name Changes:

Type of Angle Description
Obtuse Angle is greater than 90° but less than 180°
Straight Angle is 180° exactly
Reflex Angle is greater than 180°
Full Rotation is 360° exactly

What is obtuse angle with example?

An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc. ∠ PQR is an obtuse angle because it’s less than 180° and greater than 90°.
