Answer:
1. 15cm,
2. 22.5ft
3. 24in
4. 24.2m
5. 8.9m
Explanation:
1. √(9²+12²) = 15cm
2. √(8²+21²) = 22.47 ft = 22.5ft
3. 7²+x²=25²
x =√(25²-7²) = 24 in
4. √(15²+19²) =24.2 m
5. √(4²+8²) = 8.9m
all the answers related to the pythogorus theorem.
a²+b²=c²
in which a and b are the legs of the right angled triangle where c is the hypotenuse.
