Answer:
Part 1) 0.669
Part 2) x=23.78 cm
Step-by-step explanation:
Part 1) we have
cos(48°)
Using a calculator
cos(48°)=0.66913
Round to the nearest thousandth
0.66913=0.669
Part 2) we know that
In the right triangle of the figure
The cosine of angle of 18 degrees is equal to divide the adjacent side to the angle of 18 degrees by the hypotenuse of the right triangle
so
cos(18°)=x/25
x=(25)cos(18°)=23.78 cm
Answer:
2/3
Step-by-step explanation:
-5/12 ÷ -5/8
Copy dot flip
-5/12 * -8/5
The 5's cancel
-8/-12
Divide the top and bottom by -4
2/3

Answer: 300, the volume is 300 because you take 10 times 5 times 6 and you get the volume
Answer:
65 degrees :)
Step-by-step explanation:
If you have 115 degrees, and you know triangles are always 180 degrees in total, then you have to subtract 115 from 180 to get your answer for what the measures are. 180-115=65
So it's 65 degrees.
I think this is what you want to know :)
