Answer:
1. cone 2. cube
Step-by-step explanation:
a cube has 6 equal sides, a cone has one round base.
You use (y2-y1)/(x2-x1) so if you have two points (ex: (1,2) and (2,4)), plug in those number into the formula
(4-2)/(2-1) = 2/1 = 2 so the slope (or instantaneous rate of change) is 2 for those two points<span />
Answer:
D. ∠B = ∠B' = 74° and ∠C = ∠C' = 66°
Step-by-step explanation:
Given,

We know,sum of all 3 angles of a triangle is
°
Doing so ,

Simplifying all like terms,

Dividing both side by 12


Now we plug this in each angles and find their exact values.
°
°
°
Now substituting the
in angles of dilated triangle.
°
°
°
We see that all the corresponding angles are equal and as far as the options are concerned only option (D) matches.
