Answer:
x=0.9
Step-by-step explanation:
x/3=1.2/4
cross product
3*1.2=4*x
3.6=4x
x=3.6/4
x=0.9
A^2 - b^2 = (a - b)( a +b);
<span>cos^4x-sin^4x =( cos^2x + sin^2x )( cos^2x - sin^2x) = 1* cos2x = co2x.</span>
Answer:
4.5
Step-by-step explanation:
a^2+b^2=c^2
Answer:
18 + √26
Step-by-step explanation:
You will have to use distance formula between all 4 points to solve this. Once you have found the lengths between the points, you can add them all together. When you add them all together you should get 18 + √26 as your answer.
