Y=10°
If we're solving for the ninety degree angle, which I seem to doubt, then if 3x=90 then 2x=60 giving a missing total of 30. 30/3 equals 10
Try this solution (the way shown is not the shortest one):
The task on the left part:
1. note, the point P and R have coordinates (-4;-4) and (-3;-2).
2. using the coordinates of points P and R it is possible to make up the equation of the required line:
The task of the right part:
1. note, the common view of the equation of the line is y=kx+b, where b - an intersection point of the Y-axis and the given line; k=QR/PQ.
2. according the picture b= -5, k=4/1=5, so <u>y= -4x-5</u>
Answer:
A dilation is a type of transformation that works with scale factors and enlarges or reduces a figure, to create a new figure. Now, the composition of transformations that will create a pair of similar but not congruent triangles are - a rotation, then a dilation.
