ASSIGNMENT MATHEMATICS 1 FBM0015 CS2 GROUP 2 SEMESTER JAN 2024 LECTURER:SIR FAIZ Comath
*reading construction manual* Hello good sir! I would like to build a house. Alright sir. Have you found a plot of land for it? Whoops, I thought you would suggest me some.... It’s okay, let me show you someplace suitable. Whoa, this plot is huge! What’s the area of it?
Well, this plot is a corner plot. And it consists of two section, rectangular and triangle. 25m 30m 30m 25m 21m 28m 1.291 Area of rectangle: 30 x 25: 750m2 Area of triangle: ½ (21)(28) sin(1.291) : 282.57m2 Total area: 1032.57m2 Nice! I think making a swimming pool at the triangular section! Yeah, absolutely! What’s the height of the house next to this plot? I want my house to be taller. Oh, it’s easy! We just have to know the angle of elevation and the distance of the house from us. How are we supposed to calculate the angle of elevation?
By using clinometer. A tool that measures the angle of elevation, or angle from ground, in a right angled triangle. 59.5 5m x Tan (59.5) = x/ 5 X= 8.5m Oh great! I want my house to be 10m tall then. Sure, sir. Genuine question, wouldn’t my house fall if it is too tall? Perpendicular?! What’s that? Not if the walls are perpendicular.
When the walls are 90 degrees with each other its called perpendicular. 90° 90° How are you so good at this?? Trigonometry. THE END
