Evaluate the double integral i=∫∫dxyda where d is the triangular region with vertices (0,0),(4,0),(0,4).

mario62 [17]

$I=\displaystyle\iint_D\mathrm dA=\int_{x=0}^{x=4}\int_{y=0}^{y=4-x}\mathrm dy\,\mathrm dx$
$I=\displaystyle\int_{x=0}^{x=4}(4-x)\,\mathrm dx$
$I=8$

To verify this, we can simply find the area of the triangle using the well-known formula $\dfrac12bh$ , where $b$ and $h$ are the base and height, respectively of the triangular region $D$ . We have $b=h=4$ , so the area is $\dfrac{4^2}2=8$ , as expected.

Find m∠USW if m∠USW = 7x - 34 and m∠TSR = 4x + 9.

nikitadnepr [17]

In this question, it is given that the measurement of angles USW and TSR are 7x-34 and 4x+9 .

First we have to find the relationship between those two angles .

And these angles are vertical opposite angles which are congruent .

Therefore

$m \angle USW = m \angle TSR$

$7x-34 = 4x+9
\\
3x = 43
\\
x = 14.33$

Therefore measurement of angle USW is

$=7(14.33)-34 =66.31 degree$
