Answer:
508.4
Step-by-step explanation:
This is on delta math
Answer:
Step-by-step explanation:
cos 225 = -cos 45 = -1/√2.
sin 225 = -sin45 = -1√2.
Since it's multiplication we can Multiply the constants. In this case 4, 15, and 2. We get 120. We now then multiply the variables. We then get the answe 120mnx
Answer:
30
Step-by-step explanation:
= 170 + 15 - 5 (3+16) - 64 + 4
= 170 + 15 - 95 - 64 + 4
= 30
The sum of all angles in an octagon is given by
180*(n-2) >>>>>>>>>with n = 8
180*(8-2) = 1080 degrees
A + B = 1080 .......where
A is the <span>angle of an octagon which is twice that of the other seven angles
</span><span>
B equals the sum of the other seven angles
If we assume each angle of B is equal to each other, then
B = x+x+x+x+x+x+x = 7x
</span>
And A = 2x
The equation that results is
A + B = 2x +7x = 9x =1080
x = 120 degrees
2x = A = 240 degrees
