Answer:
x-7 represents x moved 7 units to the left.
Step-by-step explanation:
The translation: (x, y) → (x - 7, y - 4) was performed on a triangle
x is translated into x-7. 7 is subtracted from x . It means x is moved 7 units to the left
y is translated into y-4. 4 is subtracted from y. It means y is moved 4 units down.
So x-7 represents x moved 7 units to the left.
Step-by-step explanation:
this is not an isoceles triangle.
anyway, we need to remember 2 things :
1. the sum of all angles in a triangle is always 180°.
2. the sum of all angles around a single point on a line is 360° (as this point wound be the center of an invisible circle). and as the line cuts this circle in half, the angles on one side of the line around this point is therefore 180°.
so, the internal angle Q is then
180 = 50 + 55 + Q
Q = 180 - 50 - 55 = 180 - 105 = 75°
the exterior angle x at Q is then
180 = Q + x = 75 + x
x = 180 - 75 = 105°
