The value of double integration can be found by applying limits and integrating them one by one.
<h3>What is integration?</h3>
It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have:
![\rm \int\limits \int\limits_R {ye^{-xy}} \, dA \ , R = [0,2]\times[0,3]](https://tex.z-dn.net/?f=%5Crm%20%5Cint%5Climits%20%5Cint%5Climits_R%20%7Bye%5E%7B-xy%7D%7D%20%5C%2C%20dA%20%5C%20%2C%20R%20%3D%20%5B0%2C2%5D%5Ctimes%5B0%2C3%5D)
After plugging limits:

After solving the first integration:

After solving the further integration and plugging limits:


Thus, the value of double integration can be found by applying limits and integrating them one by one.

Answer:
70 degrees
Step-by-step explanation:
Angle HMK = 50 degrees
Angles LMK, MLK and MKL are equal to 60 degrees, being in a perfectly congruent triangle which they all add up to 180 degrees.
Add 60 to 50 = 110
180 - 110 = 70 degrees, equal to angle HMG.
This is because the line that angles LMK, HMK and HMG are on is supplementary.
Add up the legnths of the cable then multiply by 1.5
35+50=85
85 times 1.5=127.5
the answer is $127.50
