•*Ok first let me show you the formula for the Area of the trapezoid.
A=a+b/2 h.(I will be using the letter x for the multiplication sign)

*And here is the formula to find the height of a trapezoid
h=2 x A/a+b (2 times the Area over base "a" plus base "b")

*We need to plug in the numbers: h = 2 x 136.5/6+15
*Next, we add the two bases to get 21: 6+15=21 (h=2 x 136.5)
*Then, divide the total of the two bases (21) from the area to get 6.5: 136.5/21-6.5
*Finally we multiply 2 by 6.5: 2 x 6.5= 13
The height if this trapezoid is 13.

Hope this helps you ☺

Answer:

$m=\sqrt{2}$ inches

Step-by-step explanation:

From the diagram, it is given that the triangle is a right angle isosceles triangle (angles are 45°, 45° and 90°). This means that the two shorter sides of the triangle are equal in length and that the side $m$ can be found by using the Pythagorean theorem $a^{2}+b^{2}=c^{2}$ .

$m^{2}+m^{2}=2^{2}$ (The two shorter sides of the triangle are equivalent)

$2m^{2}=4$

$m^{2}=2$

$m=\sqrt{2}$ inches

I hope this helps :)
