If i am correct, these values should add to 360, so I do it by

140 + 110 + 62 = 312

360 - 312 = 48

So the value of the last side must equal 48.

Your answer would be x = -9. Proof:

If 9 is filled in, you would have

(3 - 5(-9))

(3 - (-45))

Then

48 + 140 + 110 + 62 = 360!

Answer:

$x = \sqrt{\frac{7}{2} }$

Step-by-step explanation:

<u><em>Explanation</em></u>

From given graph

AC = √7

Given angle ∝ = 45°

$cos\alpha = \frac{adjacentside}{Opposite side}$

$cos45 = \frac{x}{\sqrt{7} }$

$\frac{1}{\sqrt{2} } = \frac{x}{\sqrt{7} }$

$x = \frac{\sqrt{7} }{\sqrt{2} }$

$x = \sqrt{\frac{7}{2} }$

x = 1.8708

a vertical line goes through the points (6,-5). Someone plzzzz tell me what are the coordinates of the vertical line and how do

iVinArrow [24]

Vertical line is a straight line that goes up and down

this also means that all points on this vertical line will share the same x coordinate

you see that one of the points is (6,-5)
therefore the equation of the line is
x=6

Find the area of the shaded region. Round your answer to the nearest hundredth.

Lerok [7]

Answer:

1.44 units²

Step-by-step explanation:

The angle for the big triangle is 60°, so the smaller triangle is 30°

so to find the base of the small triangle you can do tan 30 = X/2 $\sqrt{3}$

so x is 2, which means that the base of the big triangle is 4.

The area of the big triangle is 1/2bh = 1/2(4)(2 $\sqrt{3}$ ) = 4 $\sqrt{3}$ = 6.93

Find hypotenuse (radius) using Pythagorean Theorem r = 4

The area of the piece of pie is $\pi r^{2} *60/360$ = 8.37

8.37 - 6.93 = 1.44
