Answer:

The measure of angle Y is 41.1°

Step-by-step explanation:

Given as :

The figure is of triangle YES

The measure of angle S = ∠a = 70°

Let The measure of angle Y = ∠b = x°

The measure of side EY = a =  10 unit

The measure of side SE = b =  7 unit

Now, According o question

<u>From The Law of Sin</u>

\dfrac{a}{Sina} = \dfrac{b}{Sinb} = \dfrac{c}{Sinc}

So, from figure

\dfrac{EY}{Sin S} = \dfrac{SE}{Sin Y}

<u>Compare with sin Law</u>

\dfrac{a}{Sina} = \dfrac{b}{Sinb}

Or, \frac{10}{Sin 70^{\circ}} =  \frac{7}{Sin x^{\circ}}

Or, \dfrac{10}{0.9396} =   \frac{7}{Sin x^{\circ}}

Or, 10.642 =   \frac{7}{Sin x^{\circ}}

Or, Sin x° = \dfrac{7}{10.642}

Or, Sin x° = 0.65777

∴ x = Sin^{-1}0.65777

i.e x = 41.1°

So,The measure of angle Y =  x = 41.1°

Hence, The measure of angle Y is 41.1°   Answer

Answer:

Therefore

m∠Y = 41.1°

Step-by-step explanation:

Given:

In Δ YSE ,

m∠S = 70°

YE = 10 = side opposite to ∠Y

SE = 7 = side opposite to ∠S

To Find:

m∠Y = ?

Solution:

In Δ ABC, Sine Rule says

\dfrac{a}{\sin A}= \dfrac{b}{\sin B}= \dfrac{c}{\sin C}

So here In Δ YSE,

\dfrac{YE}{\sin S}= \dfrac{SE}{\sin Y}= \dfrac{YS}{\sin E}

substituting the given values we get

\dfrac{10}{\sin 70}= \dfrac{7}{\sin Y}\\\\\sin Y=\dfrac{0.939\times 7}{10}=0.6577\\\\Y=\sin^{-1}0.6577=41.1\°

Therefore

m∠Y = 41.1°

Use long division to determine the quotient of the polynomials. (x3 – 7x – 6) ÷ (x – 4) Which of the following options best desc
Lelechka [254]

Answer:

The correct option is c.

Step-by-step explanation:

The quotient of the polynomials is

\frac{(x^3-7x-6)}{x-4}

We need to find the remainder by using long division method.

The dividend of the given expression is

Dividend=x^3-7x-6

Divisor=x-4

The long division method is shown below.

\frac{(x^3-7x-6)}{x-4}=(x^2+4x+9)+\frac{30}{x-4}

From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.

Therefore the correct option is c.

What is the total cost if the shirt cost $40 and 20% off
Eddi Din [679]
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.

40 × 0.20 = 8

So now you would subtract 8 from the cost of 40.

 40 - 8 = 32.

The shirt costs $32.
