What’s the range of possible sizes for side x?

1.3< x < 6.7

Step-by-step explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x> the measure of the third side of triangle

Applying the triangle Inequality Theorem

1) 4.0+2.7 > x

6.7 > x

rewrite

x< 6.7 units

2) x+2.7 > 4.0

x> 4.0-2.7

x> 1.3 units

therefore

The range of possible sizes for side x is the interval> (1.3,6.7)

1.3< x < 6.7

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
