Answer: Option 4
Step-by-step explanation:
Similar triangles have congruent angles, so this means that the sines, cosines, and tangents should be the same.
Thus, the side lengths of the triangle we want to find should be multiples of 
.
- This eliminates options (1) and (3).
Between options 2 and 4, we know that the Pythagorean theorem is not satisfied by option (2), thus we should eliminate it.
This leaves us with option (4)
Answer:
47%
Step-by-step explanation:
To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.
Answer:
x=k/4+c/4
Step-by-step explanation:
4x-c=k
4x=k+c
x=k/4+c/4
Answer:
66.56cm = perimeter
Step-by-step explanation:
First find the easy part (the rectangle)
10+10+17+17=54
subtract the part that is not really there (dashes)
54-8=46
Add the height of the circular part
46+8=54
Find the circumference of a circle with a radius of 8
2(8)(3.14)=50.24
Divide by 4 (the circumference is only 1/4 of the the actual circle in this problem)
50.24/4=12.56
Add all of it together
12.56+54=66.56
