Answer:

x = 15°

y = 59°

Step-by-step explanation:

Angles at a right angle add up to 90°

41 + y = 90

y = 90 - 41

y = 59°

Angles in a triangle add up to 180°

41 + (2x - 9) + 7x + 13 = 180

41 + 13 - 9 + 2x + 7x = 180

45 + 9x = 180

9x = 180 - 45

9x = 135

x = 135/9

x = 15°

Answer:

Vertical change of point C to B = 4.5

Vertical change of point A to D = -4

Step-by-step explanation:

Vertical change of a point is the rise of the given point.

Now we have to calculate the rise of point C to B,

y-coordinate of the point C → -2.5

y-coordinate of the point B → 2

Rise from C to B = 2 - (-2.5)

                           = 2 + 2.5

                           = 4.5

Similarly, y - coordinate of point A → 2

y - coordinate of point D → -2

Vertical change or rise = -2 - 2

                                      = -4

Therefore, vertical change of point C to B = 4.5

Vertical change of point A to D = -4

Which expression illustrates the associative property of addition? (3 19) – 12 = (3 12) – 19 3 (19 – 12) = 3 (19 12) (3 19) – 12
Gre4nikov [31]

Answer:

Associative Property

For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4.
