Solve:

harina [27]

Answer:

$x = 0$

Step-by-step explanation:

Write the number in exponential form with the base of 2:

${2}^{x - 3} = {2}^{ - 3}$

Since the bases are the same, set the exponents equals.

$x - 3 = - 3$

Cancel equal terms on both sides of the equation:

$x = 0$

If the smallest angle of a triangle is 20° and it is included between sides of 4 and 7, then (to the nearest tenth) the smallest

lawyer [7]

Answer:

$3.5$

Step-by-step explanation:

The smallest side of a triangle is formed by the smallest angle in the triangle.

To find the side opposite (formed by) the 20 degree angle, we can use the Law of Cosines. The Law of Cosines states that for any triangle, $c^2=a^2+b^2-ab\cos \gamma$ , where $a$ , $b$ , and $c$ are the three sides of the triangle and $\gamma$ is the angle opposite to $c$ .
