Answer:

x = 45

Step-by-step explanation:

The average is calculated as

average = \frac{score}{count}

here the average = 50 , thus

\frac{36+44+75+x}{4} = 50

Multiply both sides by 4

36 + 44 + 75 + x = 200

155 + x = 200 ( subtract 155 from both sides )

x = 45

Find x the missing side length of the triangle
Scilla [17]

Answer:

16.6

Step-by-step explanation:

a = 14

b = 9

c = x

a² + b² = c²

14² + 9² = x²

196 + 81 = x²

x² = 277

\sqrt{x^2} =\sqrt{277}

x = 16.6
