(x+-0.5) (x+-0.5) = -41.75 so therefore, x = -41.75
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
D) y=x+1
I am not sure though.
Answer:
5
Step-by-step explanation:
-8x + 25 = -15
-25 = -40 then
-40 divide -8 to get 5
