)Figure XYZ is reflected about the y-axis to obtain figure X’Y’Z’: A coordinate plane is shown Triangle XYZ has vertices X at 5 comma negative 4, vertex Y at 2 comma negative 4, and Z at 4 comma negative 1. Triangle X prime Y prime Z prime has vertices at X prime negative 5 comma negative 4, Y prime at negative 2 comma negative 4, and Z prime at negative 4 comma negative 1.

Which statement best describes the relationship between the two figures?

Figure XYZ is bigger than figure X’Y’Z’.
Figure XYZ is congruent to figure X’Y’Z’.
The measure of angle R is equal to the measure of angle S’.
The measure of angle R is equal to the measure of angle T’.

Answers

B. Figure XYZ is congruent to figure X'Y'Z'
All you are doing is rotating the figure so therefore you are not changing the shape or size.

What value of z makes the equation true? 7/8=z/32 Answers: A. 7 B. 8 C. 14 D. 28

Answers

This is something you call "Proportions" or two ratios equal to each other.

$(7)/(8)= (z)/(32)$

Multiply 32 and 7.

$(224)/(8) = z$

The answer is $z = (224)/(8)$ or $28$
