Answer:
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°.
75° +125° +∠T +60° = 360°
∠T = 360° -260° = 100°

Answer:
Coordinates of the image point → (-2, 9)
Step-by-step explanation:
If a point (x, y) is translated by 'h' units left and 'k' units up then the rule for the translation will be,
(x, y) → (x - h, y + k)
Rule for the translation of a point (2, 7) by shifting 4 units left and 2 units up will be,
(2, 7) → (2 - 4, 7 + 2)
→ (-2, 9)
Coordinates of the image point → (-2, 9)
"A dilation centered at the origin with scale factor to 1/2 from the origin" means that we must join O to all the vertices of the triangle,
and make the distances 1/2 of the original triangle. This is shown clearly in the picture.
The coordinates of the new triangle are A'(0,4), B'(1,-1), C'(-1,-1).

The relationship between corresponding sides in terms of their lengths:
The sides of the dilated triangle are half the length of the first triangle.</span><span>The relationship between corresponding sides in terms of their orientations.
The two triangles have the same orientation.
</span><span>The relationship between corresponding angles in terms of their measures.
The two triangles have congruent corresponding angles.</span>
Answer:
9/pi or 2.865
2.25/pi or 0.716
9/25pi or 0.115
36/pi or 11.459
Step-by-step explanation:
The formula for the volume of a cone
V= 1/3pir^2h
V= volume
pi= 3.141592...
r= radius
h= height
1) 3= 1/3pi (1)^2h
9=pi(h)
h= 9/pi or 2.865
2) 3= 1/3pi (2)^2h
9=4pih
h= 9/4pi or 0.716
3) 3= 1/3pi (5)^2h
9= 25pih
h= 9/25pi or 0.115
4) 3=1/3pi (1/2)^2h
9= 1/4pih
h= 36/pi or 11/459
