Find the missing variable for a tralezoid. A=68^2 b=<br> h=4 B=21
Bezzdna [24]
The answer is:  " 2291 units " .
____________________________________________
Explanation:
____________________________________________
Formula for "Area of a trapezoid" :
____________________________________________
Area = (1/2) * (base length 1 + base length 2) * height;

or:  A = (1/2) * (b + B) * h.

We are missing the value for "b" one of the base lengths.

However, since:  A = 68² (given) ;  B (the other base length) = 21;  and the perpendicular height, "h" = 4 ;  we can plug this values into the formula, and solve for "b" ;
________________________________________________
A = (1/2) * (b + B) * h ;  ↔  68² = (1/2) * (b + 21) * 4 ;

 ↔  <span>4624 = 2 (b + 21) = 2b + 42 ;

</span> ↔  <span>4624 = 2b + 42 ; 

</span> ↔  <span>2b + 42 = 4624 ;

Subtract "42" from each side of the equation:

     2b + 42 - 42 = 4624 - 42 ;

to get:   2b = 4582 ;
</span>___________________________________________________
    Now, divide each side of the equation by: "2" ; to isolate "b" on one side of the equation; and to solve for "b" ;
___________________________________________________
             2b / 2 = 4582 / 2 ;
___________________________________________________
 to get:    b = 2291 units.

Answer:

<em>In </em><em>the </em><em>above</em><em> </em><em>figure</em>

<em>both </em><em>the </em><em>sides </em><em>are </em><em>equal</em><em> </em><em>then</em><em> </em><em>angle </em><em>between</em><em> </em><em>them </em><em>will </em><em>also </em><em>equal</em>

<em>so,</em>

<em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>3</em><em>x</em><em>+</em><em>1</em><em>)</em><em> </em><em>=</em><em> </em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>7</em><em>5</em><em> </em>

<em>x </em><em>=</em><em> </em><em> </em><em>1</em><em>7</em><em>5</em><em>/</em><em>7</em>

<em>x </em><em>=</em><em> </em><em>2</em><em>5</em>

hence angle will (25 *2) +2 =52

other angle is( 25*3)+1 = 76

<em>hope </em><em>it </em><em>helps</em><em> </em><em>and </em><em>your </em><em>day </em><em>will </em><em>fine</em>

Please help me on this
avanturin [10]

Answer:

1. 8

2. 11

3. 14

4. 17

Step-by-step explanation:

When there is a number next to a number inside parenthesis, it means you multiply those together. Don't forget to use PEMDAS either. So you first multiply 3(and whatever number is inside) and then add 5. Hope this helped :)
