Answer:
sin(40°)
Step-by-step explanation:
Trigonometric functions such as sine, cosine, tangent whose short forms are sin, cos, tan respectively are <u><em>repetitive functions</em></u> which repeat itself after every integral multiple of 2π radian or 360°. It means if you add or subtract 360° from any input of trigonometric function the output of the function won't change.
It means sin(θ) = sin(θ - n×360°) = sin(θ + n×360°)
similarly cos(θ) = cos(θ - n×360°) = cos(θ + n×360°)
and tan(θ) = tan(θ - n×360°) = tan(θ + n×360°)
where n is an integer.
So, by this sin(400°) = sin(400° - 360°) = sin(40°)
Answer:
54 square meters
Step-by-step explanation:
Similar figures have corresponding lengths as equal ratios.
Smaller trapezoid's base is given 12 and larger trapezoids base is given 18, so the scale factor is 
<em>this means the lengths of larger is 1.5 times lengths of smaller.</em>
<em />
In terms of area, the scale factor is squared. Hence the scale factor for area is 
<em>this means the area of larger is 2.25 times the area of smaller.</em>
<em />
Now, Let area of smaller trapezoid be x so we can say: 
<em>to nearest square meter, </em><em>x = 54 meters squared</em>
115 is the outlier, and it results in the mean being lower than it would have been.
Answer:
Leon multiplied 8 by 2 when he should have raised 8 to a power of 2.
The multiplication of two negative values in step 4 should result in a positive value.
The correct answer should be 83.

I did it i was correct
Answer:
A, D, E
Step-by-step explanation:
x and y should add up to 120 bc 180- 60= 120 so thats the only value we're missing
