Answer:

The measure of ∠D = (Q) = 28.81

Step-by-step explanation:

Tan(Q) = perpendicular/ base

In this case perpendicular is BC and base is DC

BC =25 DC = 45

Tan(Q) = BC/DC

Tan(Q) = 25/ 45

Tan(Q) = 5/ 9

(Q) = tan^ -1 (0.55)

(Q) = 28.81

a number is 429

where 4 is underlined

For finding value of digits , we always start from right side

Firstly , it comes unit digit

multiply by 1

Secondly , it comes tenth digit

multiply by 10

Thirdly , it comes hundredth digit

multiply by 100

we can see that 4 is third digit from right

so, it will at hundredth place

To find it's value, we multiply by 100

so, we get

Simplify (9y²-x² )÷ (xy+3y²)

alexdok [17]

Step-by-step explanation:

$\cfrac{(9y²-x² )}{ (xy+3y²)}$
$\cfrac{3 {}^{2} (y) {}^{2} - x}{3(y {})^{2} + xy }$
$3 {}^{2 - 1} y {}^{2 - 2 - 1} - x {}^{2 - 1}$
$3 y { }^{ - 1} - x$

$\cfrac{3}{y} - x$

Therefore,the answer is $\cfrac{3}{y} - x$ .

[Some of the steps I didn't show,try by yourself,to find!]
