Answer:
Well everyone does
Step-by-step explanation:
Answer: B
Step-by-step explanation:
To find angle C, you want to look at 14 and 16. From angle C, we have 
. This tells us to use tangent. We use the values to fill into tangent.
In order to find the value of C, we have to find inverse tangent.
Answer:
A and B, A and C
Step-by-step explanation:
A and B touch at T same as A and C. The tangent is in between the two circles but through the touching points. B and C share the tangent but externally since at T it does not pass in between them.
Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
