Since he’s already at -15, if he writes a check for 7 then he’s subtracting more from his account.
So, -15-7=-22
The correct answer would be (4,-5)
13 feet
Pythagorus is used
25 + 144 = 169
169 is 13 to the second power etc
This question has to do with making an approximation based on the diagram of the angle. Angle KLM is an obtuse angle meaning it is larger then 90° but is also less than 180°. The only choices that lie within this range are choices B and D. However, it is safe to assume that angle KLM is closer to 180° than to 90° based on the diagram, therefore the answer must be choice B.
I hope this helps.
