Answer:

x = 2

y = 5

1 = 80

2= 10

3 = 100

Step-by-step explanation:

Complementary angles add to 90.

So 5(x+14) + 2(10-y) = 90. Solve for x.

5x + 70 + 20 -2y = 90

5x - 2y = 0

Supplementary angles add to 180.

So 5(x+14) + 121-3x-3y = 180. Solve for x.

5x + 70 + 121 -3x -3y = 180

2x - 3y = -11

This creates a system of equations. Solve using elimination.

5x - 2y = 0  ------>  10x - 4y =0

2x - 3y = -11 ------> 10x -15y = -55

                           _____________

                                      11y = 55

                                         y = 5

Substitute y=5 into the equation to find x.

2x - 3(5) = -11

2x - 15 = -11

2x = 4

x=2

Find the measure of each angle by substituting x = 2 and y =5 into each angle.

10. Which representation of a transformation on a coordinate grid does not preserve orientation? A. (x, y) → (4x, 4y) A. , , , ,
marta [7]

Answer:

D. (x, y) → (x, −y)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

The orientation shows how an object is arranged. Rotation, translation and dilation preserves orientation while reflection does not preserve orientation.

The transformation (x, y) → (4x, 4y) shows the dilation by a scale factor of 4. Dilation preserve orientation.

The transformation (x, y) → (−y, x) shows the rotation of a point 90 degrees counterclockwise. Rotation preserve orientation.

The transformation (x, y) → (14x, 14y) shows the dilation by a scale factor of 14. Dilation preserve orientation.

The transformation (x, y) → (x, −y) shows a reflection over the x axis. Reflection does not preserve orientation.

How many triangles can you make with straws the lengths 2,1,2 inches
Yuliya22 [10]

Answer:

You can't make any triangle

Step-by-step explanation:

we know that

The T<u>riangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

so

In this problem

2+1>2

3>2 -----> is not true

therefore

You can't make any triangle.

PLZZZZ ANSWER ASAP TY

So c is located at -50 from 0, and d is 50 from 0. we could just say that c+d=? 

0 is 50 away from c, so c=50, d is 50 away from 0 so d=50, now we just add 50+50=100, answer is 100
