Answer:

A'(-3, 5), B'(1, 7), C'(2, 3)

Step-by-step explanation:

The rule $(x,\,y) \to (x-1,\,y+2)$ means to subtract 1 from all the x-coordinates and add 2 to all the y-coordinates. (It also means move each point 1 unit to the left and 2 units up.)

2) Find the angle measures of a triangle if the first angle is thirty-one degrees more than

Charra [1.4K]

Answer:

4x+88=180

First angle is 54°

Second angle is 23°

Third angle is 103°

Step-by-step explanation:

Let x be the second angle. First angle is 31+x. Third angle is 2*(31+x)-5 = 62+2x-5 = 2x+57

All angles in a triangle add upto 180°

31+x+x+2x+57 = 180

4x+88=180

Subtract 88 from both sides,

4x = 92

Divide by 4,

x = 23°

31+x = 54°

2x+57 = 2*23 + 57 = 46+57 = 103°

Find m∠KHG. m∠IHG = 161° m∠IHK = (3x + 4)° m∠KHG = (7x + 7)° help??

Mrac [35]

For this case we have to, if we look at the figure, the IHG angle is given by the sum of the IHK and KHG angles.

We have to:

$IHG = 161$

So, as mentioned above we have:

$(3x + 4) + (7x + 7) = 161\\3x + 4 + 7x + 7 = 161$

We add similar terms:

$10x + 11 = 161\\10x = 161-11\\10x = 150\\x = \frac {150} {10}\\x = 15$

Thus, the KHG angle is given by:

$7 (15) + 7 = 105 + 7 = 112$

Answer:

The KHG angle is 112 degrees

Solve for d. 2(d − 10) = 18 d =

snow_tiger [21]

Here,

2(d - 10) = 18

d = ?

Now,

2(d - 10) = 18

or, 2d - 20 = 18

or, 2d = 18 + 20

or, 2d = 38

◆ d = 19

I hope it's help you...

Thanks♥♥
