Answer:
A
Step-by-step explanation:
ABC triangle is 1/2 the size of DEF triangle. In order to transform ABC to DEF, the scale has to be doubled and the point on the y-axis has to move down to 10
1) 2x-1 or x=1/2
2) 5a-16 or a=16/5
The sum of exterior angles in total: 360 degrees
6th angle = 78+50+89+37+65= 319
Then 360-319= 41 degrees
Answer:
1/30 of an hour
Step-by-step explanation:
The refrection of a point or set of points across the line y = x will result in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.
Given that the vertices of a triangle are P(-8, 6), Q(1, -3) and R(-6, -3), the vertices of the triangle formed by the refrection Ry=x<span>(ΔPQR) are P'(6, -8), Q'(-3, 1) and R'(-3, -6).</span>
