Answer:
A
Step-by-step explanation:
sin A=(opposite side)/hypotenuse=a/c
cos A=(adjacent side)/hypotenuse=b/c
tan A=(opposite side)/(adjacent side)=a/b
So you need to divide 1000 by 125 which is 8. Which then you times by two to equal the two kilograms. So he needs to fill the cup up 16 times.
Answer: a
Step-by-step explanation:
3x+12=5x-21
-5x -5x
-2x + 12 = -21
-12 -12
-2x=-33
x = 16.5
We can find the area of the big triangle, and subtract it from the small 4 x 2 triangle.
bh/2
3*8/2
12
bh/2
2*4/4
4
12 - 8
4 unit²
To find the perimeter:
a² + b² = c²
9 + 64 = c²
73 = c²
√73 = c
√73 + 3 + 8 + 2 + 4
√73 + 17
Hope this helps!
