Step-by-step explanation:
Angle 1 = 105 degrees (co-interior angles on a set of parallel lines)
Angle 2 = 75 degrees (corresponding angles on a set of parallel lines)
Hope you have a nice day :)
Answer:
AB= 156
Step-by-step explanation:
96-30 =66
A=66
66+90 = 156
6 1/4 = 25/4
(25/4)*3 = 75/4
(72+3)/4 = 72/4 + 3/4 = 18 3/4 miles per hour

Hi there!
To find the surface area, we need to find the area of all of the faces. The triangle face = 4 x 6, and the rectangular faces = 2(5 x 12) + 1(6 x 12). All we are doing is simply finding the area of each face and adding it together. The area of the triangles = 24, and the area of the rectangles = 192. Then, add the two values to get 216cm^2.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
