Mark Brainliest please


See the image for the drawing
Let’s say the side BC is extended till D

1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.

1. Find area of hexagon
Number of sides(area of triangle)
(6)1/2(11)(9.5)=313.5
Multiply by 2 since there are two hexagons
=627

2. Find area of the 6 rectangles
Number of sides(area of rectangle)
(6)(11)(20)=1320

3. Add area of both hexagons and the rectangles
627 + 1320= 1947

Therefore, the surface area of this prism is 1947

I hope I helped :)
