∠ BDE = 360 – (125 + 55 + 70) = 110 ∠ ADE = 180 - ∠ BDE = 180 – 110 = 70 In ∆ADE and ∆ABC ∠ ADE = ∠ ACE (each 70 ° ) ∠ A = ∠ A (common) ∆ADE 
∆ACE (By AA rule) (AE)/(AB) = (DE)/(BC) (21)/(AB) = 7/15, AB = 45 cm
15.78% of (287 + 302) + 12³ = ?% of 170 + 8 × 14 + 3²
19.22 × 11.99 + 142.15 = ?
? = 26.08 + 18.99 × 25.07
20.99 × √4.09 × 30.09 = ? × √195.99 × 15.09
24.11% of 249.99 + √143.97 ÷ 12.02 = ?

2660.03 ÷ 69.98 x 49.9 = ? + 10.32
(4.89)2 + √144.35 - √121.25 = ?
Solve the following expression and calculate the approximate value.
398% of 388 + 129% of 323.89 – 430.93
12.5% of 6400 + (17 × 25) = ?% of 2200+ 125
