Answer:
Step-by-step explanation:
All the triangles are right angle triangles. The longest side is the hypotenuse while the other sides are the opposite side and adjacent side. To determine the missing sides, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
a) 29² = b² + 20²
841 = b² + 400
b² = 841 - 400 = 441
b = √441 = 21
b) 5² = 2² + a²
25 = 4 + a²
a² = 25 - 4 = 21
a = √21 = 4.58 to 2 decimal places
c) c² = 9² + 6²
c² = 81 + 36 = 117
c = √117
c = 10.82 to 2 decimal places
