Answer:
1/ √2
Step-by-step explanation:
Here, we want to get the value of sin 45
Mathematically the sine is the ratio of the opposite to the hypotenuse
The opposite here is 1 while the hypotenuse is
√2
so the value of sin 45 will be;
1/ √2
Do 2x2 first which is 4 and then 5+12 which is 17 . 17/4 is 4.25
A) 2.85g+3.15c
B)2.85(8.4)+3.15(6)=$42.84
