Group
![[x^2 + 10x] + [10x + 100] = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%5E2%20%2B%2010x%5D%20%2B%20%5B10x%20%2B%20100%5D%20%3D%20%28U%20%2B%20V%29%5E2)
Factorize each group
![x[x + 10] + 10[x + 10] = (U + V)^2](https://tex.z-dn.net/?f=x%5Bx%20%2B%2010%5D%20%2B%2010%5Bx%20%2B%2010%5D%20%3D%20%28U%20%2B%20V%29%5E2)
Factor out x + 10
![[x + 10][x + 10] = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%20%2B%2010%5D%5Bx%20%2B%2010%5D%20%3D%20%28U%20%2B%20V%29%5E2)
So, we have:
![[x + 10]^2 = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%20%2B%2010%5D%5E2%20%3D%20%28U%20%2B%20V%29%5E2)

Step-by-step explanation:
Answer:
x = 128
x - 23 = 105°
Step-by-step explanation:
x - 23° = 105° because these angles are corresponding
x = 105 + 23
x = 128
The value of the angle marked x - 23 = 105
Answer:
4.71 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the above question,
r = QR = 3 units
θ = angle QRS= 90 = 90°
The length of the arc is calculated as:
2 × π × 3 × 90/360
= 4.7123889804 units
Approximately to the nearest hundredth = 4.71 units
