Answer:
x = 38°
Step-by-step explanation:
x and the 142° angle are supplementary angles, meaning they add up to 180°
x + 142° = 180°
Subtract 142 from both sides.
x = 38°
I got the answer 8x^3+1 by putting the values in the above formula
8=1.88+a
Subtract 1.88 on both sides.
a= 6.12
I hope this helps!
