Answer:
53°
Step-by-step explanation:
17² = 18² + 20² - 2(18)(20) cos Q
289 = 324 + 400 - 720 cos Q
289 = 724 - 720 cos Q
-435 = -720 cos Q
0.6042 = cos Q

Q = 52.83

Answer:

Step-by-step explanation:
8^2+5^2=c^2
64+25=c^2
89=c^2
c=
<-- this is the length of the rectangle at the bottom
2^2+(
)^2=c^2
4+89=c^2
c=
<-- length of dotted line (diagonal)
Answer:
k= 20
Step-by-step explanation:
You start with this equation:
k-16=4
Add 16 on both sides.
k=4+16
Simply.
k=20
If you want to check your answer, you can just plug 20 into where k is back into the equation:)
