Hello! So, the sum of the angles of a triangle is 180 degrees. There’s already an angle that is 60 degrees. So, there are 120 degrees left to be found. You set this formula up as 3y = 120. Divide each side by 3 to isolate the y. When you solve that, you should get y = 40.
2y = 80 degrees
y = 40 degrees
Hello There!
It would be 9(3w + 4) (3w + 4)
Hope This Helps You!
Good Luck :)

Answer:
use the formula pi r 2 and simply multiply 3.14 times 16.
Answer: the answer is x=−2
If you have
2 KNOWN sides & 1 Angle ;
Use Cosine Rule
If you have 3 KNOWN sides,
Also Cosine Rule
If you have
2 KNOWN angles & 1 side,
Use SINE rule
If it's a right-angled triangle, use SOH CAH TOA
Hopefully this helps
