In which quadrant would the point (9.-10) be located?
a) Quadrant 1
b) Quadrant 2
c) Quadrant 3
d) Quadrant 4

D

Step-by-step explanation:

Start with the 9. It goes to your right. It is on the plus x axis.

You are either in quad 1 or quad 4

We need the - 10 to decide which.

+ 10 would go up and that would mean quad 1

- 10 mean going down so you are in Quad 4

the answer is d

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
