Answer:
1.53
Step-by-step explanation:
because 21 minus 19.47= 1.53
Because the angles are supplementary, they add to 180 degrees.
I solved this by dividing

which gives me 30 degrees.
multiply 30 by 5 gives you 150.
and 30 + 150 = 180
The answer is x=−1.3125
I hope this helps.
Have a "AWESOME" day! :)
