CHECK ATTACHMENT FOR THE DIAGRAM.
Answer:
Angle 7 is 76°
Step-by-step explanation:
From the diagram, notice that angle 4 = angle 5
That is,
Δ4 = Δ2
Because vertically opposite angles are equal.
Δ4 = 7x
Δ2 = 126
So
126 = 7x
Divide both sides by 7
x = 126/7 = 18
Again, angle 5 = angle 7
Δ5 = Δ7
Because vertically opposite angles are equal.
Since Δ5 = (4x + 4)°
And x = 18
Then
Δ7 = 4(18) + 4 = 72 + 4 = 76°
Answer:
375%
Step-by-step explanation:
15 ÷ 4 = 3.75
3.75 x 100
= 375
Answer:
Step-by-step explanation:
a). Lines of symmetry of the circle given in the picture are,
x = 0
y = 0
y = -x
y = x
b). Since, a circle has infinite lines of symmetry (diameters) so the other lines of symmetry of the given circle will be all infinite numbers of the diameters.
c). Other symmetry this circle has a point symmetry.
(Looks the same when rotated by 180°).
Pretty sure that would be y = 5
