Well I believe the surface area of the box would be 9 because diameter is the whole length of a circular or spherical object. Therefore, we would do 3 times 3 to find the area. I hope this helps!
Well, alternate exterior angles are congruent. They will have the same measure. They are equal to each other.
6x+5= 7x-4
Add 4 to both sides.
6x+9= 7x
Subtract 6x on both sides.
9=x
Now, plug in 9 for the measures of the angles.
6(9)+5
54+5= 59
7(9)-4
63-4= 59
The angles equal 59 degrees.
I hope this helps!
