Step-by-step explanation:
<h3>
Answer: B) Only the first equation is an identity</h3>
========================
I'm using x in place of theta. For each equation, I'm only altering the left hand side.
Part 1
cos(270+x) = sin(x)
cos(270)cos(x) - sin(270)sin(x) = sin(x)
0*cos(x) - (-1)*sin(x) = sin(x)
0 + sin(x) = sin(x)
sin(x) = sin(x) ... equation is true
Identity is confirmed
---------------------------------
Part 2
sin(270+x) = -sin(x)
sin(270)cos(x) + cos(270)sin(x) = -sin(x)
-1*cos(x) + 0*sin(x) = -sin(x)
-cos(x) = -sin(x)
We don't have an identity. If the right hand side was -cos(x), instead of -sin(x), then we would have an identity.
Answer:
20
Step-by-step explanation:
According to the question,five over 25 divided by 100
Can also be written as
5/25/100
So
5/25×100
1/5 ×100
20
So the final answer is 20
J. -8 is the correct answer
Answer:
Ms. sim is not correct
Step-by-step explanation:
Rectangular Prism A
4 x 5 x 6 =
4 x 5 = 20
20 x 6 = 120 cm cubed
Rectangular Prism B
3 x 7 x 6 =
3 x 7 = 21
21 x 6 = 126
