I think it is C-two real solution
Answer:
y = 100°
Step-by-step explanation:
x = 40° (vertical angles are congruent)
y is an exterior angel of a triangle that has two opposite internal angles, x (40°) and 60°.
According to the exterior angle of a triangle, thus:
y = 40 + 60
y = 100°
To solve the problem, we need to use the relation between the angles to find a relation involving x. Then we need to solve for x and use that value to determine the measure of the desired angle.
The diagram shows you ...
... ∠KIJ + ∠JIH = ∠KIH
The problem statement tells you ∠KIJ = ∠JIH, so we can substitute ∠JIH in the above equation to get
... ∠JIH + ∠JIH = ∠KIH
... (4x+3) + (4x+3) = (12x)
... 8x +6 = 12x
... 6 = 4x . . . . . . . subtract 8x
Since we want to know the value of 12x, we can go directly there
... 18 = 12x . . . . . . multiply the above equation by 3
m∠KIH = 18°
Answer:
Step-by-step explanation:
The rule for reflecting a given point (x,y) over the y-axis is .
That means we reflect a given point over the y-axis by negating the x-coordinate of the given point.
If one of the options is "negate the x-coordinate of the preimage", then this is the correct option.
If you have: among the options, then it is the correct answer.
Answer:
.09
Step-by-step explanation:
It is this because if you divide 9 by 100 it will equal .09.
