In ∆ TQR, 90° + 40° + x = 180°(Angle sum property of a triangle) Therefore, x = 50° Now, y = ∠ SPR + x (ext. angle equal to sum of opp. int angles) Therefore, y = 30° + 50° y = 80°
20.05% of 220.05 – 15.15% of 99.99 × 2.02 = ?
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
(18 2 – 17 2) x (1/5) + ? = 148
What is the value of (6 + 4) ×12/4 + 5 – 3?
192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 250 + 26 ÷ 2 × ? = 207
84% of 8400 + 42% of 6120 =?
√(24²+285-8²-172) = ?²
