Step-by-step explanation:

This problem is about the sum of adjacent angles. From the problem, we have:

According to these angles, we can deduct that the share the same vertex, like this:

Replacing given expressions en values, we have:

Now, knowing the value of the variable, we can find the measure of each angle:

take it another
