Answer:
- the angle at H is 120 degrees
- the missing segment is DC
Step-by-step explanation:
The "roof" FGH is bigger than 90 degrees because FG and GH are not acute. .
Without instruction we can assume FGH is 120 degree.
This means GHF is 30 degrees to complete the triangle FGH.
So the angle around H, or JHG is 90 + 30 = 120 degrees
For the ratio, we can simply look at the comparison between the small figure DJHGF
and the large figure DCBAE, and we see that the denominator
DJ in the small figure is DC in the large figure.
Answer:
(x, y) = (-3, -6)
Step-by-step explanation:
The second equation can be used to write an expression for y:
... -5x -21 = y . . . . . . . add y-21 to both sides
This expression can be substituted for y in the first equation:
... 6 = -4x +(-5x -21)
... 27 = -9x . . . . . add 21, collect terms
... -3 = x . . . . . . . divide by -9
Using this value of x in the expression for y, we find ...
... -5(-3) -21 = y = -6
The solution is x = -3, y = -6.
