For all triangles, right-angled included, it is the multiplication of the base length times the perpendicular height x half.
Algebraically
A = 0.5bh
For a right-angled triangle it is the base length times to length of right angled (perpendicular) line times one half.

What is Pythagoras?
It is the longest side in a right-angled triangle. You can find it by squaring and adding together the two shorter sides and when you get the answer, find the square root of the number.
How do you find to sine of an angle?
To find the sine ratio of a right-angled triangle divide the opposite by the hypotenuse. For example: 4/5 = 0.8 units and sine-1(0.8) = 53.13010235 degrees.
Refer to the triangle below its a picture of a Right-angled triangle a on the left b on the bottom and c on top If a-3 and b3 find the length of c rounded to the nearest hundredth?

The formula used to find the area of a triangle is?
area= bash X height / by 2
A kite string makes an angle of 41point3 degrees with the level ground when the kite is 114 ft high how long is the string?
In effect, you have a right-angled triangle with an adjacent angle of 41.3o and an opposite side of 114 feet. There are several ways to find the length of the string (which in effect is the hypotenuse of the triangle), but in this case, the quickest way is to use the sine ratio. For any right-angled triangle: sin angle = opposite/hypotenuse. Rearranging the equation: hypotenuse = opposite/sin angle hypotenuse = 114/sin 41.3o hypotenuse = 172.7268362 feet. Therefore, the string is 173 feet in length correct to the nearest foot.
