The sum of the interior angles of all triangles is 180 degrees. This means you can set all the angles' expressions equal to 180 and solve algebraically for x.

180 = 3x + 2x + x
180 = 6x
30 = x

Answer:
30°

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°

Which pair of points tells you the relation is NOT a function?
tankabanditka [31]

Answer:

(1,4) and (1,0)

Step-by-step explanation:

These have the same first coordinate and different second coordinates, meaning that it cannot be a function. For it to be a function, the x coordinates have to be different numbers.
