Answer:
x=12
Step-by-step explanation:
Both these angles are *supplementary* to each other, this means that (10x-20) and (6x+8) will both equal 180 degrees.
1. Add 10x - 20 and 6x + 8 together
By adding them together, you get 16x - 12
2. Since both of them added together would also equal 180, this means that 16x - 12 = 180
3. Use the additive inverse property and add 12 to both sides. This gives you 16x = 192
4. In order to isolate x, divide 16 on both sides.
192/16 = 12
Therefore, x is 12

Answer:
1770
Step-by-step explanation:
No calculator is needed.
When you fill in the numbers, you get ...
1 = (x/1770)^(-0.8)
The only way the value will be 1 is if the fraction is 1:
x/1770 = 1
The only way the fraction will be 1 is x = 1770.
