Answer:
QR = 12 (cm), RP = 10 (cm)
Step-by-step explanation:
Corresponding sides of the triangles:
XY : PQ, YZ : QR, ZX : RP.
For similar triangles ratios of corresponding sides are the same
XY : PQ = 4 : 8 = 1 : 2
YZ : QR = 1 : 2
ZX : RP = 1 : 2
6 : QR = 1 :2, QR = 12 (cm)
5 : RP = 1 : 2, RP = 10 (cm)
See below
y=-2x + 3
y = -2*3x
Both equations are lines.
Two lines will intersect at one point
I will set the two equations equal and solve for the x coordinate.
-2x+3 = -6x
Add 2x from each side
3 = -4x
Divide by -4
-3/4 = x
Now find y
y = -6x
y = -6(-3/4)
y = 18/4 = 9/2
The solution is ( -3/4, 9/2)
Given that the left angle =
The right angle across from it
The other two angles are x and x.
We know that the sum of angles at a point equals 360 degrees.
Therefore,
The value of x is approximately 38.5 degrees.
The equation would be .05x+50=100 Then you would solve for x
0.75
