Answer:
The two angles are 10 degrees and 170 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Let the angle be called "x", and the supplementary angle be called "180-x"
Converting words to math: x-160=180-x
Add x to both sides: 2x-160=180
Simplify: 2x=20
Divide by 2: x=10
Let me know if this helps!
(1.31 * 10^8) / (5.28 * 10^3)
= 0.2481 * 10^5
= 2.48 * 10^4
= 24,810 miles approximately
