Answer:
Step-by-step explanation:
Move the decimal to the left once on both of them and time the numbers together
The last one 7(30)-7(7) because if you do it then it is 7(23) which doesn’t make sense because it is 27 we need to find
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
Simple, to find the percentage you scored on your test, take
What you got= 69
Total=75
Divide,
69/75=0.92
Finally, multiply by 100.
0.92*100=92
<span>You got a 92% on the math test.</span>
When you write the equation of a circle in the form
Then the center of the circle has coordinates 
and the radius is 
So, in your case, the center of the circle is
