Answer:
9 yd
Step-by-step explanation:
A cube consists of 6 square faces.
Divide the surface area by 6 for the area of one face
486 ÷ 6 = 81 yd²
The area of a square is
A = s² ( s is the side length )
Here A = 81, then
s² = 81 ( take the square root of both sides )
s =
= 9
Thus side length is 9 yd
Answer:
45
Step-by-step explanation:
I think so i dont know
Angle 1 = 115°.
Because angle 4 = 65°, we know that the angle on the other side on 4 (with no number on it) must equal 180° when added to 65°. This is because they are supplementary angles, meaning that they add up to 180°. So if you do 180°-65°, you should get 115°, which is the measure of that angle.
Since the lines are parallel, that means that angle 1 and the angle outside of 4 must be equal, which means that angle 1 = 115°.
Hope this helps!
800 * ( 6.45 / 100 ) = 8 * 6.45 = 51.6$ ;
