Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>39</u></em><em><u>°</u></em></h2>
Step-by-step explanation:
As per condition,
3x - 17° + 2x + 2° + 90° + 90° = 360°
<em>[</em><em>Since</em><em> </em><em>angle</em><em> </em><em>sum</em><em> </em><em>property</em><em> </em><em>of</em><em> </em><em>quadrilateral</em><em>]</em>
=> 3x + 2x - 17 + 2 + 90 + 90 = 360
=> 5x = 360 + 17 - 2 - 90 - 90
=> 5x = 195
=> <em><u>x = 39 (Ans)</u></em>
Okay, here you go :)

Have a Wonderfull day.
Just to go into more detail than I did in our PMs and the comments on your last question...
You have to keep in mind that the limits of integration, the interval
, only apply to the original variable of integration (y).
When you make the substitution
, you not only change the variable but also its domain. To find out what the new domain is is a matter of plugging in every value in the y-interval into the substitution relation to find the new t-interval domain for the new variable (t).
After replacing
and the differential
with the new variable
and differential
, you saw that you could reduce the integral to -1. This is a continuous function, so the new domain can be constructed just by considering the endpoints of the y-interval and transforming them into the t-domain.
When
, you have
.
When
, you have
.
Geometrically, this substitution allows you to transform the area as in the image below. Naturally it's a lot easier to find the area under the curve in the second graph than it is in the first.
