Answer:
Step-by-step explanation:
x+165 = 180
x = 180 - 165
x = 15
Answer:
To complete the square the equation would be 2(x+4)^2-29
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
Answer:
x=-4
Step-by-step explanation:
-4x -7 - 3x + 4 = 25
-7x=25-4+7
x=-28/7
x=-4
5.9 is what your answer should be! :) Hope this helps! :)
