1/√2
Step-by-step explanation:
Imagine a right-angled triangle, for e.g. Triangle ABC,
Where
B = 90°
Remember your Toa Cah Soh.
sin 45° = opposite / hypotenuse
If theta = 45°
Angles A and C = 45° (Sum of angles in a triangle equal = 180°)
Since theta are the same, we can also deduce that the length AB and BC are the same.
Take for example AB = BC = 1 = opposite
By the Pythagorean theorem,
AB² + BC² = AC²
1² + 1² = AC²
2 = AC²
AC = √2 = hypotenuse
Therefore:
sin 45° = opposite / hypotenuse
sin 45° = 1/√2
Answer:
5.6 ounces OR 5 and 3/5
Step-by-step explanation:
Any line y=m is horizontal. The y-coordinate of any point lying on such line is m, only x-coordinates change.
If y=1, then two points on the line are (x₁,1) and (x₂,1).
So, the slope of this and any horizontal line is 0.
The answer is a.
256 in2 = s2
sqrt(256) = 16 → side length = 16
rectangle width = 16, length = 16+2 → 18
18 x 16 = 288 in2
Answer:
Maybe the figure of this question is a triangle.
If so...the answer comes something like this....
Hope it helps! :)
