Answer:

\large\boxed{Q1.\ \sin\theta=\dfrac{40}{41}}\\\boxed{Q2.\ 30^o}

Step-by-step explanation:

Q1.

\sin\theta=\dfrac{y}{r}

\text{We have}\\\\r=1\to(\text{radius of the unit circle}),\\\\y=\dfrac{40}{41}\to\text{from the given point}\ \left(\dfrac{9}{41},\ \dfrac{40}{41}\right)\\\\\text{Substitute:}\\\\\sin\theta=\dfrac{\frac{40}{41}}{1}=\dfrac{40}{41}

Q2.

<em>look at the picture</em>

210° is in III Quadrant. Therefore the reference angle for θ is:

210° - 180° = 30°

72 is 40% of what number?
Tanya [424]
All you have to do to find what number a certain number is a certain percentage of is to divide the known number by the percentage that it is reduced by.
To do this, we must first convert the percentage into a decimal. To do this, we can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.

40% = 0.4

Now, we divide the known by the percentage/decimal.

72 / 0.4 = 180

72 is 40% of 180.
Hope that helped! =)

Anestetic [448]

Step-by-step explanation:

In set a, every element in the domain has only 1 image in the range. This is called a one-to-one correspondence.

However in set b, there is a many-to-one correspondence as more than 1 element in the domain has the same image.
