Answer:

1.) a= √50

2.) a = (10√3)/3

3.) a = 6

4.) a =√5

5.) a = (3√2)/2

6.) a =2

7.) a=12

8.) a= 3√3

9.) a= 6√2

10.) a= 2√3

11.) a= 2√2

12.) a=8

Step-by-step explanation:

30-60-90 triangles

hypotenuse = 2(short leg)

short leg = 1/2(hypotenuse)

long leg = short leg(√3)

short leg = long leg/√3

45-45-90 triangles

hypotneuse = leg(√2)

2.) If ZA = (20 – 2m)º and ZD = (m – 130°, what is the value of m? ​
vivado [14]

Answer:

m = 50

Step-by-step explanation:

∠ D and ∠ A are vertically opposite angles and are congruent , then

m - 130 = 20 - 2m ( add 2m to both sides )

3m - 130 = 20 ( add 130 to both sides )

3m = 150 ( divide both sides by 3 )

m = 50

Which transformation was applied to figure A to form figure B?
PtichkaEL [24]

Answer:

B

Step-by-step explanation:

Let point N has coordinates (0,0), then figure A has vertices at points (-3,0), (-7,0), (-7,4) and (-3,4). Figure B has vertices at points (3,1), (7,1), (7,-3) and (3,-3).

1. Translation 10 units to the right has the rule

(x,y)→(x+10,y).

Then vertices of the figure A have images:

  • (-3,0)→(7,0);
  • (-7,0)→(3,0);
  • (-7,4)→(3,4);
  • (-3,4)→(7,4).

2. Translation 3 units down has the rule

(x,y)→(x,y-3).

Then images are

  • (7,0)→(7,-3);
  • (3,0)→(3,-3);
  • (3,4)→(3,1);
  • (7,4)→(7,1).

As you can see these points are exactly the vertices of the figure B.

Can someone please help?????? Is it stretch or dilation????Or another one?????
Serggg [28]
Stretch should be correct.

It can't be reflection or rotation because that would result in a congruent figure (same side lengths). A dilation would result in a similar figure, where each of the sides is multiplied by a constant value, which is not the case here since one side remains the same and the other changes.
