The exterior angles of a pentagon are (m+5)°, (2m+3)°, (3m+2)°, (4m+1)° and (5m+4)° respectively. Find the measure of each angle
olga nikolaevna [1]

Answer:

Step-by-step explanation:

Sum of exterior angles of any polygon =360°

Sum of exterior angles of polygon = 360°

m + 5  + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360

m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4  = 360  {Combine like terms}

15m + 15 = 360 {Subtract 15 from both sides}

        15m = 360 - 15

        15m = 345 {Divide both sides by 15}

           m = 345/15

m = 23

m + 5 = 23 + 5 = 28°

2m + 3 = 2*23 + 3 = 46 + 3 = 49°

3m + 2 = 3*23 + 2 = 69 + 2 = 71°

4m + 1 = 4*23 + 1 = 92 + 1 = 93°

5m + 4 = 5*23 + 4 = 115 + 4 = 119°

Ming drew the model below to represent the equation 24 + 12 = blank x (8 + 4). A model with 3 rows of 8 and 3 rows of 4. What is
Mila [183]

Given:

The equation is:

24+12=\_\_\times (8+4)

A model with 3 rows of 8 and 3 rows of 4.

To find:

The missing value in Ming's equation.

Solution:

We have,

24+12=\_\_\times (8+4)           ...(i)

A model with 3 rows of 8 and 3 rows of 4. Using this information, we get

24+12=3\times 8+3\times 4

Taking out the common factor 3, we get

24+12=3\times (8+4)               ...(ii)

On comparing (i) and (ii), we get the missing value is 3.

Therefore, the missing value in Ming's equation is 3.
