Answer:
The first 3 terms in the expansion of 
, in ascending power of x are,
coefficient of 
in the expansion of 
= (240 - 192) = 48
Step-by-step explanation:
= 
= 
+ terms involving higher powers of x
= 
+ terms involving higher powers of x
so, the first 3 terms in the expansion of , in ascending power of x are,
Again,
= 
Now, by inspection,
the term comes from k =5 and k = 6
for k = 5, the coefficient of is , 
= -192
for k = 6 , the coefficient of is, 
= 240
so, coefficient of in the final expression = (240 - 192) = 48
Answer:
∠1 - 40°
Step-by-step explanation:
∠1 - 40°
b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.
∠2 - 140°
b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.
∠3 - 40°
b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.
∠4 -
b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.
∠5 - 35°
b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

Answer:
AC=18
Step-by-step explanation:
To find AC, use the Pythagorean Theorem. Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b². 12²-8²=b²
144-64=b²
80=b²
√80=√b²
8.94427191=b
That is for one of the two right triangles that make up the tent. Since there are 2 triangles, 8.94427191 only equals BC or AB. So, multiply 8.94427191×2=17.88854382 to find the length of AC.
AC= 18
