Can you please help and explain how to do this

x = -3

Step-by-step explanation:

Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)

Then, we can say in equation form:

<CDH + <HDE = 144

replacing with their expressions in terms of x:

x + 93 + 57 + x = 144

solving for x:

2 x + 150 = 144

2 x = 144 - 150

2 x = - 6

x = -3
