d= 52

e= 77

f=51

Step-by-step explanation:

look at d and e just use the number across

then multiple

d(52) and e(77) by 2 so

52×2=104

77×2= 154

so it would be 258

now subtract 258 from 360 and that gives you

102

102÷2 = 51

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^
