PLEASE HELP ASAP!!!!!! WILL GIVE BRAINLYIST!!!!!! 4 QUESTIONS!!!!
1. The scale on a scale drawing is 1 : 30. What should you do with each measurement on the drawing to get the actual dimensions? Provide an example of a drawing that uses this scale. Include both the original and new dimensions. You may use graph paper, screen share or the whiteboard to show your example.

2. Can a triangle have both an obtuse and a right angle? Explain and provide an example.

3. Can you form a triangle with angle measurements of 50o, 50o and 100o? Explain why or why not.

4. Find the missing angle of the triangle with angle measurements of 75o and 80o. What is the missing angle? Explain how you found your answer.

1. If the scale is 1 : 30, you would have to multiply every measurement by 30 in order to get the actual dimensions. You might have to make a drawing yourself. You could just draw a rectangle with the scale 1 : 30 and then multiply all the sides of the rectangle by 30 to get the actual dimensions.

2. No, a triangle cannot have both an obtuse and a right angle. A right angle is 90 degrees, and an obtuse angle is greater than 90 degrees.

However, the three angles of a triangle must add up to 180 degrees in total. The right angle and the obtuse angle would add up to greater than 180 degrees, which makes it impossible to make a triangle.

3. No, you cannot. Again, the angles of a triangle must add up to 180 degrees. 50 + 50 + 100 = 200, which is greater than 180.

4. The missing angle is 25 degrees, or 25o. Again, the angles add up to 180 degrees. 75 + 80 = 155. 180 - 155 = 25, so the third angle must be 25 degrees.
