Question

Find the length of side CB in the following right triangle

Round your answer to the nearest tenth.

Answer 1

CB = 1.4 cm

Explanation:

Given is a right angled triangle.

`{x}^(2) + {1.4}^(2) = {2}^(2) \\ {x}^(2) + 1.96= 4 \\ {x}^(2) = 4 - 1.96 \\ {x}^(2) = 2.04 \\ x = √(2.04) \\ x = 1.42828569 \\ x \approx 1.4`

CB = 1.4 cm

Answer 2

6cm

Explanation:

a2 + b2 = c

(1.4)2 + (2)2 = c

1.96 + 4 = 5.96

=5.96cm (round it)

final answer = 6cm
