Answer:
x = 17
∠A = 114°
Step-by-step explanation:
In the figure attached, the complete question is shown.
From the figure, we know that:
∠A = ∠B
Replacing with the expressions, we get:
6x+12 = 3x+63
6x - 3x = 63 - 12
3x = 51
x = 51/3
x = 17
∠A = 6(17)+12
∠A = 114°
Answer:
The value of x will be 8
Step-by-step explanation:
We have given that 
We have to find the value of x
As 
For finding the value of x we have to square both side
On squaring both side
We done squaring both side for easy simplification

So x = 8
So the value of x will be 8
So answer will be 8
The expression of integral as a limit of Riemann sums of given integral
is 4
∑
from i=1 to i=n.
Given an integral
.
We are required to express the integral as a limit of Riemann sums.
An integral basically assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinite data.
A Riemann sum is basically a certain kind of approximation of an integral by a finite sum.
Using Riemann sums, we have :
=
∑f(a+iΔx)Δx ,here Δx=(b-a)/n
=f(x)=
⇒Δx=(5-1)/n=4/n
f(a+iΔx)=f(1+4i/n)
f(1+4i/n)=![[n^{2}(n+4i)]/2n^{3}+(n+4i)^{3}](https://tex.z-dn.net/?f=%5Bn%5E%7B2%7D%28n%2B4i%29%5D%2F2n%5E%7B3%7D%2B%28n%2B4i%29%5E%7B3%7D)
∑f(a+iΔx)Δx=

Hence the expression of integral as a limit of Riemann sums of given integral
is 4
∑
from i=1 to i=n.
