Answer:
sum of interior angle of a triangle is 180 degree
so,
3x +7 + 2x+7 +3x+6 = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/ 8
x = 20
May it will help you
Answer:

Step-by-step explanation:
Given

Required
Integrate
We have:

Let

Differentiate

Make dx the subject

So, we have:



Express x^(10) as x^(5*2)

Rewrite as:

Recall that: 

Integrate

Substitute: 

Hence:

Answer: 17 or -18
Step-by-step explanation:
x^2+x=306
x^2+x-306=0
(x-17)(x+18)=0
x-17=0
x=17
x+18=0
x=-18
..i think this is the right answer
