In the rhombus, angle 1=9x, angle 2=y+x, and angle 3=15z. Find the value of each variable. The diagram is not to scale.
notka56 [123]
From the diagram, all three angles are 90° (Diagonals of a Rhombus)

Angle 1 = 9x = 90
⇒ 9x = 90
x = 90/9
x = 10


Angle 2 = y + x = 90
⇒ y + x = 90
since x = 10,
y + 10 = 90
y = 90 - 10
y = 80


Angle 3 = 15 z = 90
⇒ 15z = 90
z = 90/15
z = 6

Answer is Option C
<span>C. x = 10, y = 80, z = 6</span>

This diagram shows triangles ABC and PQR.
Stels [109]

Answer:

<h3>A reflection across the line x=3, a reflection across the x-axis and a dilation with a scale factor of 2, because each side is double.</h3><h3>Step-by-step explanation:</h3>

We know that the first transfomration is a rotation 90° clockwise.

Notice that vertex R is at the same horizontal coordinate than vertex C, which means the second transformation must include a reflection across the line x=3, a reflection across the x-axis and a dilation with a scale factor of 2, because each side is double.

It is difficult to override a presidential veto?Why do you think is it difficult? Do you think thisgood thing? Why or why not?
Vanyuwa [196]
It is difficult to overthrow a presidential veto because each house has to have a two-thirds majority vote to overthrow The veto. it is difficult because 2/3 is more than 1/2 and it has to be in each house so it is very difficult. I think this is a good thing because if Congress wanted to pass a bill the president did not like then it is hard for them to pass it and the president is the leader so he should make the big decisions.
