Answer:
Step-by-step explanation:
In any triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse, or longest side, of the triangle (o/h).
Therefore, we have:
The reference triangle is a right triangle and therefore, the properties of
the reference triangle are similar to right triangle properties.
The correct options are as follows;
- The reference triangle always have a leg perpendicular to the <u>x-axis</u>, the hypotenuse is positive, and θ is the angle adjacent to the <u>x-axis and hypotenuse</u>.
<h3>Reasons</h3>
The reference triangle is formed by the construction of a perpendicular
to the x-axis from the terminal side of an angle, oriented in the standard
position.
Therefore;
- The reference triangle is a right triangle that always has a leg perpendicular to the x-axis.
- The hypotenuse is taken as positive, given that the magnitude of the hypotenuse is the square root of the sum of the squares of the legs.
- In the first quadrant, the reference angle, θ, is the same as the standard position angle and it is given by the angle formed between the x-axis and the hypotenuse side.
The correct options are therefore;
In Trigonometry it is important that the right triangle (reference triangles)
have a consistent orientation. The reference triangles always have a leg
perpendicular to the <u>x-axis</u>, the hypotenuse <u>positive</u> and the θ is
adjacent to the <u>x-axis and hypotenuse</u>.

Answer:
32m
Step-by-step explanation:
because we know that 3cm = 4 m, we can replace the top length with 4m, we also know that 6cm must equal 8m because of 3cm ×2 = 6cm so 4m ×2 = 8m. now we know 2of the sides so the area is just 4m ×8m because area = length times width. 4m × 8m = 32m
Answer:
5-Cy/r = d
Step-by-step explanation:
C=r(5-d)/y
Multiply each side by y
Cy=r(5-d)/y *y
Cy=r(5-d)
Divide each side by r
Cy/r=r(5-d)/r
Cy/r=(5-d)
Subtract 5 from each side
Cy/r - 5 = 5-d-5
Cy/r - 5 = -d
Multiply by -1
-Cy/r + 5 = d
5-Cy/r = d
