Imagine that you need to create a scale drawing of this sign. The scale drawing will be used to create a mold that will be used to manufacture the sign. Use the grid to make a scale drawing of this sign. Include a key to show the relationship between the dimensions in the scale drawing and the dimensions of the actual sign. Label all sides in the scale drawing. Show your work

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
