Answer:
45
Step-by-step explanation:
Together, these two angles form a flat line which is 180 degrees
(x + 7) + (4x - 52) = 180
5x - 45 = 180
+ 45 + 45
5x = 225
x = 45
Answer: First Number Line
Step-by-step explanation:
Sum of angles in a triangle = 180
2x – 5 + <span>3x + 10 + 90 = 180
5x + 95 = 180
5x = 85
x = 17
</span>2x – 5 = 2(17) - 5 = 29
3x + 10 = 3(17) + 10 = 61

A reflection is a type of rigid motion, along with translation, rotation, and glide reflection.
The relationship between them is the flipping of an object across a reflection line without changing shape or size, the only thing that changes is the position of the object.
The derivative is always nonnegative, so it doesn't change sign, therefore there is no turning point.
