Answer:
y = sin x/2
Step-by-step explanation:
y = a.sin.bx
a = y max= 2
y = a.sin.bx = 2.sin.bx
sin.bx = sin x/2
b=1/2
so
y=sin x/2

Answer:
45°
Step-by-step explanation:
All triangles are 180°.
So, we must first add up all of the other numbers:
80° + 55° = 135°
Next, we must find how much more we need to get to 180°:
180° - 135° = 45°
So, x = 45°
And, if you want to make sure. Just add up the numbers and make sure the sum is 180.
80 + 55 + 45 = 180
I hope this helps you out ; )
This is the answer I calculate .If the answer is wrong, I am sorry about this
Answer:
False
Step-by-step explanation:
It is False. 1 is the identity element for multiplication, because if you multiply any number by 1, the number doesn’t change. Identity elements are specific to each operation (addition, multiplication, etc.). So while 1 is the identity element for multiplication, it is NOT the identity element for addition.
