Answer: 8
Step-by-step explanation:
Pythagorean theorem - a^2+b^2=c^2
a^2+15^2=17^2
a^2+225=289
(subtract 225 from both sides)
a^2=64
(sq root both sides)
a=8
You would take 9x3 and get 27 and then add that to 21 which is 48 and then divide 48 by 3 and get 16 so 16in each case

Answer:
37.74
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. The one applicable here is ...
Sin = Opposite/Hypotenuse
sin(32°) = 20/x
x = 20/sin(32°)
x ≈ 37.74
You can use the symbol over 13 or you can write it like
10 square root (13)
The answer to that is 36.0555127546
Hope this helps!
