=================================================
Explanation:
Points R, O, and A are midpoints of sides XY, YG, and XG respectively.
Because of this, we know that the points cut those sides into two equal halves.
To elaborate, we know the following three facts:
Point R is the midpoint of XY, so XR = RYPoint O is the midpoint of YG, so YO = OGPoint A is the midpoint of XG, so XA = AGThe diagram shows that YO = 14, so OG must be 14 units long as well.
The diagram also shows XA = 8. Since XA = AG, we know that AG = 8.
-----------------------------
Use this information to find the perimeter of triangle XYG.
Perimeter of XYG = sum of all the sides
Perimeter of XYG = (XY) + (YG) + (XG)
Perimeter of XYG = (22) + (YO+OG) + (XA+AG)
Perimeter of XYG = 22 + (14+14) + (8+8)
Perimeter of XYG = 66
-----------------------------
Then we cut this in half to get the perimeter of triangle ROA.
We do this because each segment of ROA is half that of the corresponding segment of XYG. The midsegments (RA, RO, AO) are cut in half and are parallel to the opposite side.
So,
Perimeter of ROA = (1/2)*(Perimeter of XYG)
Perimeter of ROA = (1/2)*(66)
Perimeter of ROA = 33

y=5x-4y = 5 x − 4
y=-x+2
Answers
Answer:
Y= x+2 " substituting value of y
Step-by-step explanation:
Y=5x-4y = 5x - 4
or, 5x - 4(x+2) = 5x - 4
or, 5x - 4x+ 8 = 5x-4
or, x +8 = 5x - 4
or, 0= 5x - x - 4-8
or, 0= 4x - 12
A pair of tangents to a circle which is inclined to each other at an angle of 60 degree are drawn at ends of two radii. The angle between these radii must be :
Answers
Answer:
The angle between these radii must be 120º.
Step-by-step explanation:
According to Euclidean Geometry, two tangents to a circle are symmetrical to each other and the axis of symmetry passes through the center of the circle and, hence, each tangent is perpendicular to a respective radius. We represent the statement in the diagram included below.
Then, we calculate the angle of the radius with respect to the axis of symmetry by knowing the fact that sum of internal angles within triangle equals 180º. That is to say:
[tex]\theta = 180^{\circ}-90^{\circ}-30^{\circ}[/tex]
[tex]\theta = 60^{\circ}[/tex]
And the angle between these two radii is twice the result.
[tex]\theta' = 2\cdot \theta[/tex]
[tex]\theta' = 120^{\circ}[/tex]
The angle between these radii must be 120º.

Step 2: Solve for r
Distribute: 13 - 8r + 10 = -7 - 8rCombine like terms: -8r + 13 = -7 - 8rAdd 8r on both sides: 13 ≠ -7Here, we see that 13 does not equal -7. ∴ r has no solutions.
