A road sign is in the shape of a regular pentagon. What is the measure of each angle on the sign? Round to the nearest tenth. Se

dangina [55]

Answer:

Option D) 108 degrees

Step-by-step explanation:

We are given the following in the question:

A regular pentagon.

Thus, all the angles of the pentagon are equal.

Angle sum property of pentagon:

In a pentagon, the sum of all the interior angle of a pentagon is 540 degrees.

Measure of each angle =

$=\dfrac{\text{Measure of angle}}{\text{Number of angle}} = \dfrac{540}{5} = 108^\circ$

Thus, the measure of each angle on the sign is 108 degrees.

Option D) 108 degrees

Brian was asked to write x72 as a product of 2 powers with the same base in 4 different ways, using only positive exponents.

Oksana_A [137]

The equivalent expression to the value given using the laws of indices is ${x}^{4(18)}$

Evaluating the options given based on the laws of indices :

${x}^{8}. {x}^{9} = {x}^{8 + 9} = {x}^{17}$
${x}^{35}. {x}^{47} = {x}^{35 + 47} = {x}^{82}$
${x}^{4(18)} = {x}^{4 \times 18} = {x}^{72}$
${x}^{24}. {x}^{3} = {x}^{24 + 3} = {x}^{27}$

Therefore, the only expression which would give a correct way of representing ${x}^{72} \: is \: {x}^{4(18)}$
