Hey do you need to show your work for these? I found an answer key
Step-by-step explanation:
We need to use law of cosines
c²=a²+b²-2abcos(C)
let x= angle xzy
plugging in what we have the equation looks like
17²=22²+20²-2*22*20*cos(x)
289=484+400-880cos(x)
.676136364=cos(x)
x=47.45754235
b.)
The smallest angle should be opposite to the smallest side
Using the law of cosines again we get
9²=13²+17²-2*13*17*cos(x)
81=458-442cos(x)
.852941176=cos(x)
x=31.46697634

Answer:
A, C
Step-by-step explanation:
The values listed (least-to-greatest) are ...
{-5, -2, 0, 2}
All of these values are integers.
Not all of these values are between -4 and 2. (-5 is outside that range)
All of these values are less than 5.

The true statements are A and C.
Answer:
x = 20 / √3 = 20√3 / 3
Step-by-step explanation:
AC² = AD² + BC² = x² + x² = 2 x²
AF² = AC² + CF² = 2 x² + x² = 3 x²
3 x² = 20² = 400
x² = 400/3
x = 20 / √3 = 20√3 / 3
