Question

5. If possible, find the missing side length labeled with a question mark. If no possible,explain why

Answer 1

To find the missing side length, set up a proportion with the given scale/actual ratio and solve for the missing side.

Step-by-step explanation:

To find the missing side length labeled with a question mark, we can use the given scale/actual ratio. The ratio tells us that for every 1 unit on the scale, there are 20 units in the actual length. We can set up a proportion between the scale length and the actual length to solve for the missing side. For example, if the scale length is 1 unit, the actual length would be 20 units. If the scale length is ? (question mark), the actual length would be ? x 20 units. By cross-multiplying and solving the proportion, we can find the value of the missing side.

Answer 2

10

Step-by-step explanation:

I think is 10 because they are different triangles but both with the same measure, as you can see both angles are the same [36] and both sides of the triangle too [6] so when you divide the base [20] by 2 , 20÷2=10
