Please helppp meee outttt

9

Step-by-step explanation:

10p+12p+5p+148+149

27p+297=540

I got the 540 because it has five angles -2 equals three triangles * 180 equals 540

Subtract 297

27p=24

divide by 27

P=9

9°

Step-by-step explanation:

Sum of the interior angles of any polygon is given = (n-2)180°

where n is the no. of sides

Sum of the interior angles= (5-2)180= 3×180°=540°

Therefore, 10p+12p+149°+148°+5p= 540°

=>27p+ 297°= 540°

=> 27p= 243°

=> p= 243°/27

=> p= 9°

5 5/6 becomes the mixed number 35/6, and 2 2/3 becomes the mixed number 8/3, which can be rewrittten as 16/6.
                                              3*17
Then:  35/6 + 16/6 = 51/6 = =  17/2 (answer)
                                              3 * 2
