124.3 feet.
We are looking for the side opposite the angle we know. We have the side adjacent to this angle; opposite/adjacent = tangent:
tan 73 = x/28
Multiply both sides by 28:
28 tan 73 = x
124.3 = x
We have
tan 12.5 = 60 / adj rearrange as
adj = 60 / tan 12.5 = about 270.64 m
Answer:
40
Step-by-step explanation:
that angle it a full 180
and 1 side shows as 90
so do 90-50=40
Exact Form:
x=√7, −√7
Decimal Form:
x=2.64575131… ,−2.64575131…
Answer:
1) The reflection of a preimage (x, y) across the line y = x gives the image (y, x)
Therefore, the the coordinates of the points L, M, and N interchange to give an image of the triangle that is apparently rotated 90° clockwise, on the opposite quadrant and equidistant from the line y = x
2) Where the line segment drawn from point L to the reflecting line is horizontal, and the line segment drawn from point L to the reflecting line is horizontal, the two line segment will be of the same length and separated vertically separated vertically by a distance equal to the sum of the absolute values of the x and y coordinates of the point L
When the line segment from point L is drawn perpendicular to the reflecting line, the line segment from point L' drawn perpendicular to the reflecting line will meet the the perpendicular line segment at the same point of intersection of the line from the point L and the reflecting line
3) Yes
4) This is so because, reflection of a preimage unto an image is a form of rigid transformation, therefore, the effect of the transformation operation will be similar when each point is individually considered.
