Danielle built a ramp with a stopping block at the bottom for her scout troop’s pinewood derby. she wants to paint the top and sides of the ramp. danielle calculated the area by adding the areas of 2 triangular faces and 3 rectangular faces from the ramp and 6 rectangular faces from the block. did danielle calculate the area correctly? if not, what was her mistake? a. yes, danielle calculated the area correctly. b. no, danielle needs to remove 1 rectangle from the ramp and 1 rectangle from the block. c. no, danielle needs to add 1 triangle to the ramp and remove 1 rectangle from the block. d. no, danielle needs to remove 1 triangle from the ramp and add 1 rectangle to the block.

Actually its b).

Step-by-step explanation:

She only wants to paint the top and sides of the ramp therefore you will have to take off the bottom parts of the ramps aka b).

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
