Answer:
No
Step-by-step explanation:
(x,y)=(4,-1)
73x+5y=7
73*4+5*(-1)=287
____________________________
175x−3y=17
175*4-3*(-1)=703
Answer: Choice C) 115 degrees
--------------------------------
Explanation:
The three angles are 42, 73 and 65 degrees. Let's call them x,y, and z respectively
x = 42
y = 73
z = 65
To find an exterior angle for x, we subtract the given angle x from 180
180-x = 180-42 = 138
The exterior angle adjacent to angle x is 138 degrees. This isn't listed so we move on
Do the same for y
180-y = 180-73 = 107
This isn't listed either. So we move on
Repeat for angle z
180-z = 180-65 = 115
This is listed as choice C. That's why choice C is the answer
15-3/40=12/40=3.3
So, your answer is 3.3
Hope this helps:)
