Answer:
sin(4π/21)
Step-by-step explanation:
Step 1: Rearrange expression
sin(π/3)cos(π/7) - cos(π/3)sin(π/7)
Step 2: Use sin(A ± B)
sin(π/3 - π/7)
Step 3: Evaluate
sin(4π/21)
And we have our answer!
Since the interior angles of a triangle equal 180°, then 180-45=135.
Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.
Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.
However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180
Answer: I believe it would be 9 feet tall.
Step-by-step explanation:
The statues shadow is 2 times larger than the childs shadow so you would multipy the childs height by 2
$16
First you find how much one egg cost which is 3.84/12 (0.32)
Next multiply 0.32 by 50 which would be 16
