Answer:
59°
Explanation:
If you add the angles 99° from angle C in the top shape and add 22° on the bottom shape it will give you 121°. When you get this subtract it from 180°
180°-121°= 59°
So, it's 58°
You can check by adding 180°+121°+59° = 180°

Step-by-step explanation:
The number of ants in his farm after 12 weeks is 218.
Step-by-step explanation:
Step 1:
It is given that there are 15 ants initially and the ant population increases by 25% each week.
This is an exponential rate of increase that can be modeled by the following equation:
Number of ants after n weeks = Initial number of ants * 
Step 2:
Rate of increase = 25% = 25 / 100 = 0.25
Number of weeks = 12
Number of ants after 12 weeks = 15*
= 218.27 (rounded off to 218)
Step 3:
Answer:
The number of ants in his farm after 12 weeks is 218.
