Answer:

50°

Step-by-step explanation:

Transformation is the movement of one point from its initial location to a final location. If an object is transformed, all its points are transformed. Types of transformation is reflection, dilation, rotation and translation.

If an object is translated, it maintains its shape and size as well as the length of its sides and angles, only the location changes.

If polygon LMNP with ∠M of 50° is translated 5 units right and 4 units down to a new point, M' has the same angle measure. Hence ∠M' = 50°

A triangle has two sides of length 1 and 8. What is the smallest possible whole-number length for the third side?
valkas [14]

Answer:

8

Step-by-step explanation:

For the smallest possible length, this has to be one of the shorter sides. Let the length of this side be x.

So, by the triangle inequality theorem, 1+x>8, which means x>7.

So, the smallest possible whole number length is 8.

Which expression is a factor of 21x2 + 13x – 20?A. 3x – 4B. 7x - 5C. 7x + 4D. 3x + 5
LUCKY_DIMON [66]

Answer:

B. 7x - 5

Explanation

Given the expression 21x^2 + 13x – 20, to get which of the given expression is a factor we will have to factorize the equation first as shown;

21x^2 + 13x – 20

= 21x^2 + 28x - 15x - 20

= 7x(3x+4) -5(3x+4)

= (7x-5)(3x+4)

Hence one of the factors is 7x - 5

PLEASE ANSWER. WILL GIVE BRAINLIST TO THE FIRST THAT ANSWERS
Elza [17]
First you would take both radius' and add them. Once you add them, subtract the sum by 42. that will give you the distance between the gap of the circles. now that you have that distance, add 19 and 11 and your result is your final answer.

The midpoint of DG is M(-1,5). One endpoint is D(1,4). Find the
irina1246 [14]

Answer:

G(-3, 6)

Step-by-step explanation:

midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )

Substitute the coordinates of M and D into the formula:

( - 1,5) = ( \frac{x1 + 1}{2} , \frac{y1 + 4}{2} ) \\- 1=\frac{x1 + 1}{2}& ,&5&=  \frac{y1 + 4}{2} & \\ - 1(2)= x1 + 1&, & 5(2) &= y1 + 4  &\\  - 2= x1 + 1&, &10 &= y1 + 4 &\\   x1=  - 2 - 1&,& y1 &= 10 -  4 &\\  x1=  - 3&, &y1& =6  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: &

Thus, the coordinates of G is (-3,6).
