Math Problem Statement
Solution
The image presents two triangles, and , where it is stated that these triangles are similar. To find the value of , let's use properties of similar triangles.
Step-by-step explanation:
Step 1: Identify corresponding sides
Since , the ratios of corresponding sides will be equal. The corresponding sides are:
- and
- and
- and
Step 2: Write the proportions of corresponding sides
Using the property of similar triangles, we set up the following proportion:
We are given the lengths:
- (since )
- (since )
Step 3: Set up the ratio for and
We will use the third ratio for this calculation:
Substitute the known values:
Step 4: Solve for
Now, cross-multiply to solve for :
Thus, the value of is 3.75.
