Answer:
x = 48
Step-by-step explanation:
First, We know that it a supplementary angles
Note:
Supplementary angles are angles measures add up to 180 degrees.
Complementary angles are angles measure add up to 90 degrees.
Hence, it 180 degrees.
Then You see that "42 degrees" Hence 180 - 42 =138 Then You see that Box in the corner that is a complementary angles which also means 90 degrees..
138 - 90 =48
Therefore it 48, 90 ,138
Now Let's find x..{ I have a picture below}
You see the red line? It equal to the 42 degrees..
The Blue box lines makes a 90 degrees..
Hence it the same 180 - 42 - 90=48
Thus, x = 48
