The expression is equivalent to r^(m-n)
22 percent
110000 divided by 22= 5000
110000 - 5000= 105000
Answer: 1. ∠A= 80.75° 2. 41.79 
Step-by-step explanation:
Since, According to the sines low,

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

⇒ 
⇒ 
⇒ A = 80.75°
2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1
=34.86 + 6.93
= 41.79 square cm
4, 10, 4, 10. 10*4 gives area of 40. 10+10+4+4 gives 48 as shown in question
