The sum of 3 and a number is between -2 and 17.
kumpel [21]

Answer:

The number, x = { -5 < x < 14}

This means x is any integer between -5 and 14

Step-by-step explanation:

From the statement, let the number be x

3 + x = y; y = { -2 < y < 17}

This means that y is any integer between -2 and 17

Therefore, x = y - 3

Subtract 3 from the limits of y

i.e. -2 - 3 = -5 and 17 - 3 = 14

Hence, x = { -5 < x < 14}

Find the missing side or angle.
alexandr402 [8]

Answer:   <em>a = [ 65.8]</em>

Step-by-step explanation:

<em>A = 18°</em>

<em>B = 28°</em>

<em>b = 100</em>

<em>a = [ x ]</em>

\dfrac{100}{sin \: 28^{o} } =\dfrac{x}{sin \: 18^{o} } \\\\\dfrac{100}{0.4694715628} =\dfrac{x}{0.3090169944} \\\\x=\dfrac{0.3090169944 \cdot 100}{0.469715628} \\\\x=65.78810\dots \\x \approx 65.8
