U is 50 because supplementary 180-130=50
And so knowing that now
50+65+x=180 (because all triangles are equal to 180)
Add 50 and 65
115 +x=180
Subtract 115 on both sides
X=65
The answer is A

6x-4bracket(2x-5)>8 or 5x+9<2x-21
Yuri [45]

The solutions to the given inequalities are x < 6 OR x < -10

<h3>Linear Inequalities </h3>

From the question, we are to solve the given inequalities

The given inequalities are

6x - 4(2x - 5) > 8 or 5x + 9 < 2x - 21

First solve,

6x - 4(2x - 5) > 8

Clear the bracket

6x -8x + 20 > 8

6x - 8x > 8 - 20

-2x > -12

Divide both sides by -2 and flip the sign,

That is,

-2x/-2 > -12/-2

x < 6

For,

5x + 9 < 2x - 21

Subtract 2x from both sides

5x - 2x + 9 < 2x - 2x -21

3x < -21 -9

3x < -30

Divide both sides by 3

3x/3 < -30/3

x < -10

Hence, the solutions to the given inequalities are x < 6 OR x < -10

Step-by-step explanation:

 we know that'

The box displays the diagonal measurement of a tv.

so

Applying the Pythagoras Theorem

Let

d -----> the diagonal of TV

d^{2}=W^2+L^2

substitute the given values

d^{2}=34.2^2+60.8^{2}

d^{2}=4,866.28

d=69.8\ in

Round to the nearest whole number

d=70\ in
