Answer:

AB = 23.4

Step-by-step explanation:

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

a^2 + b^2 = c^2

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

(22)^2 + (8)^2 = c^2

484 + 64 = c^2

548 = c^2

c = 23.409

c = 23.4 rounded to the nearest tenth

<em>Thus,</em>

<em>the missing side AB is 23.4.</em>

<em>Hope this helps :)</em>

Answer:

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.

60% expressed as a ration is StartFraction 60 Over 100 EndFraction. What is this as a fraction in its reduced form?
Leno4ka [110]

Answer:

3/5

Step-by-step explanation:

60% means 60 out of 100. For example if you get 60 marks in an exam of 100 marks. This means you got 60% marks.

Which is 60/100. This fraction can further be reduced to 6/10 [divide both numerator and denominator by 10)

6/10 = 3/5  [divide both numerator and denominator by 2)

So, the reduced form of 60% =3/5
