Answer: x+8
The term 'sum' means 'result of adding two (or more) numbers or expressions'.
Answer:
39,51
Step-by-step explanation:
Complementary angles add to 90 degrees
Let one angle be x
The other angle is x+12
x+ x+12 = 90
Combine like terms
2x+12 = 90
Subtract 12 from each side
2x+12-12 = 90-12
2x = 78
Divide each side by 2
2x/2 = 78/2
x =39
The other angle is 39+12 =51
For the fifth term, n = 5.
Just replace n with 5 in the expression.
Then evaluate the expression.
