9p = 81 degrees

Step-by-step explanation:

All the angles in a triangle equal 180 degrees in total.

So the equation would be:

9p + 7p + 4p = 180

20p = 180

p = 9

So just plug it in:

9(9)                            7(9)                        4(9)

81 degrees            63 degrees            36 degrees

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
