You see how these 2 angles marked are both inside the 2 parallel lines?
And they are on opposite side of the transversal, the line crossing the 2 parallel lines?
These 2 angles are alternate interior angles and they are equal, I think you can do the last part by yourself.
Okay we know that tangent-chords creat 90 degree angles so what we have is a right triangle with a base of 9 and a height of 12, so do Pythoagoreas Theorem and we have 81+144=225 square root of 225 is 15 and that is AJ
1/2u - 3 x u
2u x u = 2u
answer 2u - 3
Perimeter= 2 ( length + width)
2×(12+6)
2×18
=36
Answer: To find the volume of a cube, use the formula V=lwh, or Volume equals length times width times height.
