61° all triangles equal 180 so all you do is add up each of the angles then subtract it from 180
The markings indicate the figures are congruent. The orientation of both figures is clockwise, so no reflection is involved. The direction of QR appears to be 90° counterclockwise from the direction of EF, It appears as though the center of rotation is somewhere in the triangle EGS.
The transformation appears to be a 90° CCW rotation.
First, we can note that the relation between the independent and the dependent variables is a linear relation.
We will need two points: (1,3) and (2,5)
The general form of the equation of the linear line is:
y = mx + c where m is the slope and c is the y-intercept
To get the slope, we will use the following rule:
m = (y2-y1) / (x2-x1)
m = (5-3) / (2-1) = 2
The equation of the line now becomes:
y = 2x + c
To get the value of the c, use any of the given points and substitute in the equation. I will use (1,3) as follows:
y = 2x + c
3 = 2(1) + c
c = 3-2 = 1
Therefore, the equation of the line is:
y = 2x + 1
Answer:
Step-by-step explanation:
distribute 5 in parenthesis means you multipy each term by 5
5*1-5*2 g+5*4h = 5-10g+20h
