Answer:

<X = 36

<Y = 72

<W = 108

<Z = 144

Step-by-step explanation:

Since this shape is a quadrilateral, all angles add up to 360

x + 3x + 4x + 2x = 360

10x = 360

x = 36

<X: x

<W: 3x

3(36) = 108

<Y: 2x

2(36) = 72

<Z: 4x

4(36) = 144

Shalnov [3]

Given (-4,9) (-8,9),(-9,7,(-9,4)

...

To Find : plot the point and draw quadrilateral

Solution:

(-4,9)

go 4 left of origin and then go 9 up

(-8,9)

go 8 left of origin and then go 8 up

(-9,7)

go 9 left of origin and then go 7 up

(-9,4)

go 9 left of origin and then go join (-4,9) with (-8,9) and (-9,4) 4 up

join (-9,7) with (-8,9) and (-9,4)

If M=5x^2+7x-4 and N=-3x^2-4x+5, then M-N equals

Phantasy [73]

Answer:

8x² + 11x - 9

Step-by-step explanation:

M - N

= 5x² + 7x - 4 - 1(- 3x² - 4x + 5) ← distribute parenthesis by - 1

= 5x² + 7x - 4 + 3x² + 4x - 5 ← collect like terms

= 8x² + 11x - 9

Which is equivalent to sin^-1(tan(pi/4)) ? Give your answer in radians.

aleksklad [387]

We are to find the value of $sin^{-1}(tan( \frac{ \pi }{4}))$

First we evaluate tan(π/4). The value of tan(π/4) is 1.

So,

$sin^{-1}(tan( \frac{ \pi }{4})) =sin^{-1} (1)$

sin(π/2) = 1
So,
$sin^{-1}(1)= \frac{ \pi }{2}$

Thus, we can write:

$sin^{-1}(tan( \frac{ \pi }{4}))= \frac{ \pi }{2}$ radians.

So, the answer to this question is π/2 radians.
