Answer:
8,160 lei
Step-by-step explanation:
<u><em>The question in English is</em></u>
136 children came to the ice rink in the morning, and three times in the afternoon. How much money was collected on the tickets sold, if an entrance ticket costs 15 lei?
step 1
Find the total number of children that came to the ice rink
we know that
The number of children that came to the ice rink in the morning was 136
The number of children that came to the ice rink in the afternoon was (136*3)=408
To find out the total number of children that came to the ice rink , adds the number of children that came in the morning plus the number of children that came in the afternoon
so
step 2
To find out the total money collected, multiply the total number of children by the cost of one ticket entrance
so
Answer
L' (5, -1)
M' (8, -3)
N' (1, -8)
The sketch of this rotated triangle is presented below
Explanation
Rotating a given coordinate A(x, y) 90° about the origin in the clockwise direction gives a new coordinate A'(y, -x)
So, for each of these,
L (1, 5) → L' (5, -1)
M (3, 8) → M' (8, -3)
N (8, 1) → N' (1, -8)
So, to draw this image, we will mark this new rotated points on the graph, then connect the points to form triangle L'M'N'.
The sketch of this rotated triangle is presented above under 'Answer'
Hope this Helps!!!
no it is not a tangent
for it to be a tangent to the circle Angle A would have to be a right angle.
to check if its a right angled triangle, you can use pythagoras.
this shows it is not a right angled triangle because this calculation does not give us 10.3
therefore it is not a tangent and there is no right angle
