The value of angle Y is -120° because you know that angle S is half of angle Y and -60*2 equals -120°. Hope that helps!
Because the cos theta < 0 then theta must be an obtuse angle
so a^2 + b^2 < a^2
C
Answer:
If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.

Answer:SAS
Step-by-step explanation:Similar triangles are easy to identify because you can apply three theorems specific to triangles. These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS), are foolproof methods for determining similarity in triangles.
Step-by-step explanation:
6228 = 6000 + 200 + 20 + 8.
The 2s in 6228 represent 200 ; 20.
