<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .</u>
<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .b. Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.</u>

The rays corresponding to supplementary angles intersect the unit circles in points having the same y-coordinate, so the two angles have the same sine (and opposite cosines).</u>

What is function in math?
- A quantitative expression, rule, or law that describes the link between an independent variable and a dependent variable (the dependent variable).
- In mathematics, functions occur widespread, and they are essential for defining physical links in the sciences.
- A function is a type of rule that generates one output for a single output.
- This is represented by the equation y=x2. Any inputs for x result in an output for y. Given that x is the input value, we would state that y is a result of x.

Answer: 18.7
Step-by-step explanation:
Find the lengths of AB, BC, and CA
AB = = 5 ≈ 7.1
BC = = 5 ≈ 7.1
CA = = 2 ≈ 4.5
7.1 + 7.1 + 4.5 = 18.7
Answer:
x ≈ 1.32, x ≈ - 5.32
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± ( subtract 2 from both sides )
x = - 2 ±
Thus
x = - 2 - ≈ - 5.32 ( to 2 dec. places )
x = - 2 + ≈ 1.32 ( to 2 dec. places )
Answer: V= cm^3
Step-by-step explanation:
V = s³
V = (0.01)³
V=(1/100)³
V= cm^3
