Short Side on the Bottom Half of Box on the left = 20cm
Long Side on the bottom half of the box on the bottom = 15cm
Long Side on the Right all the way from bottom to top = 35cm
Angle on Top Half of Box = X

work out value.

==========================================================

2. Use Pythagorus` Theorem t o determine if the following measurements would form a right-angled triangle. 8cm, 9cm, 12cm

==========================================================

3. The Leaning Tower of Pisa is 150m tall, but it is leaning over so that a stone dropped from the top lands 5m from the base. Calculate the height of the top of the tower above ground level. Draw a diagram.

=========================================================

4. Calculate the Value of X in the Following Triangles

( 55 degrees in the triangle against the angle )
( 3.6m along the bottom of the triangle)
(right angle on the bottom left of triangle)
( X on the left short side of triangle )

=========================================================

Thanks

 

draw it on paint or something better, or even scan a drawing of it then just put onto your thread

 

alright il try

 

Eh, if i had a calculator i'd help you out lol. But i don't . And the calculator on the computer isn't as good since you don't have 'tan' 'cos' 'sin' buttons etc.
