Look at this triangle work out length AB

2√137

Step-by-step explanation:

To find AB, we can use the Pythagorean Theorem (a² + b² = c²). In this case, a = 22, b = 8 and we're solving for c, therefore:

22² + 8² = c²

484 + 64 = c²

548 = c²

c = ± √548 = ± 2√137

c = -2√137 is an extraneous solution because the length of a side of a triangle cannot be negative, therefore, the answer is 2√137.

AB = 23.4

Step-by-step explanation:

Well to AB we need to use the Pythagorean Theorem formula,

We already have a and b which are 22 and 8.

484 + 64 = c^2

548 = c^2

c = 23.409

c = 23.4 rounded to the nearest tenth

Thus,

the missing side AB is 23.4.
