If mZx = 126° Calculate mZy

Answers

< x has the same measure as the supplement of < y because they are Alternate interior angles.

Since m < x = 126°, then the supplement of < y must also be m < 126°.

To solve for y:
m < y = 180° - 126°
m < y = 54°

Therefore, the < y has a measurement of 54°

Answers

Answer:

x=15/19

Step-by-step explanation:

You have to start by multiplying the denominators by the numerators. I doesn't matter which you do first, as you can see, I chose to multiply the 6 by the 4x first.

Once that is completed, it is a simple matter of rearranging the equation so it begins with x=...

To do this, just subtract 5x and then divide by 19 on both sides to get the final fraction.

3. In the diagram below AB' is the image of AB after a reflection in AC. If mBAC4x7 and mBAB '  64 , then which of the following is the value of x?
(1) 6.25 (3) 14.25 (2) 12.5 (4) 18.75

Answers

When a line or shape or point is reflected, it must be reflected over a line.

The value of x is (b) 14.25

Reflection is a rigid transformation;

This means that:

[tex]\mathbf{\angle AC = \angle AB}[/tex]

So, we have

[tex]\mathbf{4x + 7 = 64}[/tex]

Subtract 7 from both sides

[tex]\mathbf{4x = 57}[/tex]

Divide both sides by 4

[tex]\mathbf{x = 14.25}[/tex]

Hence, the value of x is (b) 14.25

Answers

Answer:

QS = 30

Step-by-step explanation:

Since R is the mid point QR = RS

Given QR = 6x – 51 and RS = 2x – 7 then

6x – 51 = 2x – 7, isolate like terms

6x -2x = 51 -7 , combine like terms

4x = 44, divide both sides by 4

x = 11

QS = QR + RS

QS = 6x -51 +2x -7 , combine like terms

QS = 8x - 58, substitute x= 11 in the equation

QS = 8*11 -58, multiply 8 and 11

QS = 88 -58

QS = 30
