25÷100=0.25
0.25×680=170 is the answer
If you would like to solve 98 + 56, you can do this using the following step:
98 + 56 = 154
The correct result would be 154.
Let , the supplementary angle be x
then,
x + 69 = 180
x = 180 - 69
x= 111 degrees
so the supplementary angle of 69 degrees is 111 degrees
28 times 1/7 would give you 4
Answer:
the answer is 4√7
Step-by-step explanation:
Using Pythagoras Thereon
It is 16²+ 4²
