Answer: C
Step-by-step explanation:
1 1/8 = 1.125
3/4 = .75
All triangles must equal 180°. So there you have a right angle which = 90° and a 25° angle. add those together to get 115°. Now do 180-115=65°. the missing angle is 65°.
Answer:
Step-by-step explanation:
-3x + 4y = -18
8x - 4y = 28
5x = 10
x = 2
4 - y = 7
-y = 3
y = -3
(2, -3)
Are you missing something?
2xy=7
5xy=9
does not have a solution.
If you mean
2x+y=7
5x+y=9
please say so.
