Question

Please help me on finding the missing side in each triangle. Round to two decimal places when needed!

Answer 1

B=21 a=root of 21= 4.58 c= root of 117=10.81

Answer 2

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
