Homework Book : Even Questions

a) a² = c² - b²
a² = 26² - 24²
a² = 676 - 576
a² = 100m²
√100m² = √a²
10m = a



b) b² = c² - a²
b² = 39² - 15²
b² = 1521 - 225
b² = 1296cm²
√1296cm² = √b²
36cm = b





a) a² + b² = c²
8² + 9² = c²
64 + 81 = c²
145cm² = c²
√145cm² = √c²
12cm = c


b) a² + b² = c²
6² + 10² = c²
36 + 100 = c²
136cm² = c²
√136cm² = √c²
12cm = c


I thought of the height as the line going upwards↑, the base as the bottom_, and the hypotenuse is the longest leg. I used B as the unknown height.
b² = c² - a²
b² = 11² - 4²
b² = 121 - 16
b² = 105cm²
√b² = √105cm²
b = 10.2m



No the ramp is not a right triangle because the areas of the legs added up to 13m². The area of the hypotenuse on the other hand was 25m². For the shape to be a right triangle the two values would have to be equal.





Here is a video and a link to a fun-filled Pythagoras game. ←Click that for the game ☺



P.S if you see a √ its a square root symbol.
