What's is the area in square centimeters of the trapezoid

denis-greek [22]

I do not see the exact value, but this is the formula: $A=\frac{1}{2}\left(b_1+b_2\right)h=\frac{\left(b_1+b_2\right)h}{2}$

4x^2 = 28x <br> <br> Solve and explain how you arrived at the solution

dlinn [17]

Step 1: Subtract 28x from both sides.
4x2−28x=28x−28x4x2−28x=0
Step 2: Factor left side of equation.
4x(x−7)=0
Step 3: Set factors equal to 0.
4x=0 or x−7=0
Answer:x=0 or x=7

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer: $tan(V)=2.92$

Step-by-step explanation:

For this exercise you need to remember the following Trigonometric Identity:

$tan\alpha =\frac{opposite}{adjacent}$

You must observe the figure given in the exercise.

You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).

So, you can identify in the figure that:

$\alpha =V\\\\opposite=UW=35\\\\adjacent=VW=12$

Knowing these values, you can substitute them into $tan\alpha =\frac{opposite}{adjacent}$ :

$tan(V)=\frac{35}{12}$

Now you must evaluate:

$tan(V)=2.916$

Finally, rounding to the nearest hundreth, you get:

$tan(V)=2.92$
