Answer:
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication! Dilation with scale factor 2, multiply by 2.
Answer:
the value of x is 25 degrees
Step-by-step explanation:
Here, we want to get the value of x
we use an important triangle angular principle here
And the principle is that when we add two opposite interior angles, we get the value of the exterior angle on the third side
Thus, mathematically;
x + 75 = 4x
4x-x = 75
3x = 75
x = 75/3
x = 25 degrees
Answer:
Is this what you need? Also slope = 10/1 and y intercpet = -1
Step-by-step explanation:
Hi Jessicaprado539!
The constant proportionality of this equation would be the value that relates the two amounts. In this case, that would be 2/3
Answer:
A. 40
Step-by-step explanation:
A line is equal to 180 degrees. So 180-20=160. 4x=160, x=40
