Answer:
Obtuse, scalene.
Step-by-step explanation:
In ΔSVU, one angle is 120° which is obtuse angle.
So, ΔSVU is a obtuse triangle.
All the sides have different measurements. So, It is a Scalene triangle.
<span>19.9=9y-8
9y = 19.9 + 8
9y = 27.9
y = (27.9)/9
y = 3.1</span>
<u>Answer-</u>
The slope of XZ,YZ,and XY are
respectively.
<u>Solution-</u>
The coordinates of the vertices are as follows,
X = (-5, 5)
Y = (-3, -2)
Z = (4, 0)
<u>Slope of XZ-</u>

Answer:
It will be 3 in by 4 in
Step-by-step explanation:
Original dimension is 6 in by 8 in
If he scale it down by a factor of 1/2
The new dimension will be
1/2(6) by 1/2(8)
= 3 by 4
= 3 in by 4 in
