Distance formula is derived from the Pythagorean theorem. To find the distance between two points (x1,y1) and (x2,y2), all that you need to do is use the coordinates of these ordered pairs and apply the formula to those points. So the formula would be:D=square root symbol(X1-X2)2+(Y1-Y2)2. Hope I've helped you any

Answer:

b2 = 2A/h -b1

Step-by-step explanation:

The usual formula for the area of a trapezoid is ...

$A=\dfrac{1}{2}(b_1+b_2)h$

We can solve this for b2:

$\dfrac{2A}{h}=b_1+b_2 \qquad\text{multiply by $\dfrac{2}{h}$}\\\\ \dfrac{2A}{h}-b_1=b_2 \qquad\text{subtract $b_1$}\\\\ \boxed{b_2=\dfrac{2A}{h}-b_1}$

Answer the thing on screen. Make sure to use the right < or > thing

Answer:

$12 \leq v$

Step-by-step explanation:

first you subtract 7 from 7 and 12

$19\leq v+ 7\\-7 -7$

then you get $19 \leq v$

(btw the variable always goes first with these problems)

so the final answer would be $v \geq 12$

In the figure PQ || RS, find the value of x.

ki77a [65]

The value of x in the figure is 125°

And the right option is (D) 125°

To solve the problem, we use the formular for the sum of the interior angle of a polygon.

(n-2)180°

When a vertical line is drawn to touch point Q and S, it becomes a pentagon.

Pentagon: A pentagon is a polygon with 5 sides

The sum of the angle in a pentagon is

$(5-2)180 = 540$

From the figure,

∠P+∠T+∠R+∠Q+∠S = 540°

$35+200+x+90+90 = 540$

$415+x = 540$

$x = 540-415$

$x = 125$

Hence the value of x in the figure is 125°

And the right option is (D) 125°
