Question

AABC is a right-angled triangle at B. Find
a. b, if a = 24 cm and c= 7 cm
b. c, if b = 17 cm and a = 8 cm
c. a, if b = 41 cm and c = 9 cm
d. a, if b = 15 cm and c = 9 cm​

Answer 1

Answer:

1. b=√(a²+c²) = √(24²+7²)= √(576+49)=√625 =25cm
2. c=√(b²-a²) =√(17²-8²)=√(289-64)=√225=15cm
3. a=√(b²-c²)=√(41²-9²)=√(1681-81)=√1600=40cm
4. a=√(b²-c²)=√(15²-9²)=√(225-81)=√144=12cm
