A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
A function can be represented algebraically. For example, 3x+6 3 x + 6 .
A function can be represented numerically.
A function can be represented graphically.
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:
the measure of ∠A. is 87∘
Step-by-step explanation:
Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.
_________________________________________________
Given
∠A=(4x−30)
∘
∠B=(4x−14)
∘
Fir angles to be supplementary
∠A + ∠B = 180
(4x−30)
∘ + (4x−14)
∘ = 180∘
(8x -54 )∘ = 180∘
=> 8x = 180∘ + 54∘= 234∘
=> x = 234∘/8 = 29.25∘
Thus,
∠A=(4x−30)
∘
∠A=(4*29.25−30)
∘ =( 117 - 30 )
∘ = 87∘
Thus,
the measure of ∠A. is 87∘
