Answer:
<h2>
123°, 41° and 16°</h2>
Step-by-step explanation:
x - the measure of the largest angle
x - 107° - the measure of the smallest angle
¹/₃x - the measure of the third angle
x + x - 107° + ¹/₃x = 180°
2¹/₃x = 180° + 107°
⁷/₃x = 287°
x = 287°÷⁷/₃
x = 287° · ³/₇
x = 123°
x-107° = 123° - 107° = 16°
¹/₃x = ¹/₃ · 123° = 41°

Step-by-step explanation:
The amount of strontium that will remain after 40 hours is 5 g
<h3>How to determine the number of half-lives </h3>
- Half-life (t½) = 10 hours
- Time (t) = 40 hours
- Number of half-lives (n) =?
n = t / t½
n = 40 / 10
n = 4
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 80 g
- Number of half-lives (n) = 4
N = N₀ / 2ⁿ
N = 80 / 2⁴
N = 80 / 16
N = 5 g

All you have to do is 100 plus 10 is 110 plus if you need to understand it better you can use base ten blocks use one hundred block and 1 tens block is the same thing. 100 is in one block and 10 is in one tens block. Hope this helped you ( :
