I think x=90°, and z=136°

X=90 degrees
Y=134 degrees
Z=136 degrees

Angle X and the right angle of the triangle are supplementary angles. Meaning when added together, they equal to 180 degrees.

So 180-90=90

To find y, first you have to find the missing measure of the right triangle. And to do that, you use the triangle angle sum theorem.

44+90+x=180

134+x=180

Subtract 134 from both sides

X=46.

The angle with the measure 46 is supplementary to angle y

180-46=134

Angle Z is supplementary angles with the angle with the measure of 44.

So 180-44=136

Andrews [41]

Answer:

$\frac{17}{30}$

Step-by-step explanation:

→ Substitute in the numbers

$1\frac{2}{5} -\frac{5}{6}$

→ Simplify

$1\frac{2}{5} -\frac{5}{6}=\frac{7}{5} -\frac{5}{6}=\frac{42}{30} -\frac{25}{30} =\frac{17}{30}$

y= 1/2x +2

if x=0 y=2 (0,2)

if x=2 y = 1/2 *2 +2 =1+2 =3 (2,3)

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. W

Dafna1 [17]

Answer:

A. segment A double prime B double prime = segment AB over 2

Step-by-step explanation:

Triangle ABC with coordinates of:

A = (-3, 3), B = (1, -3), C = (-3, -3)

Translation (x + 2, y + 0), coordinates will be:

A' = (-1, 3), B = ( 3, -3), C = (-1, -3)

Dilation by a scale factor of 1/2 from the origin, coordinates will be:

A'' = (-0.5, 1.5), B'' = (1.5, -1.5), C= (-0.5, -1.5)

Let's find the length of AB and A''B'' using distance formula

d = √(x2-x1)² + (y2 - y1)²

AB = √(1-(-3))² + (-3 -3)² = √4²+6² = √16+36 = √52 = 2√13
A''B'' = √(1.5 - (-0.5)) + (-1.5 - 1.5)² = √2²+3² = √13

We see that

AB = 2A''B''

Now the answer options:

A. segment A double prime B double prime = segment AB over 2

Correct

B. segment AB = segment A double prime B double prime over 2

Incorrect. Should be AB = A''B''*2

C. segment AB over segment A double prime B double prime = one half

Incorrect. Should be AB/A''B'' = 2

D. segment A double prime B double prime over segment AB = 2

Incorrect. Should be A''B''/AB = 1/2
