We know that If cotA 
cotB = 1 then A & B are complementary angles it means A + B = 90˚ cot 13˚ cot 14˚ …………………….cot 76˚ cot 77˚ = (cot 13˚ cot 77˚ ) (cot 13˚ cot 77˚ ) …………………….(cot 44˚ cot 46˚ ) cot 45˚ = 1 1 ……………………………………………………………….. 1 1 = 1
What value should come in place of (?) in the given expression.
450 ÷ 9 + 75% of 160 − 64 ÷ 4 = ?
2/5 of 3/4 of 7/9 of 14400 = ?
7/3 of 4/5 of 15/56 of ? = 83
[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
What should come in place of (?) question mark in the given expression.
(25% of 320) + (3/8 of 400) − 30 = ?
45% of 360 - 160 + ? = √324
187 ÷ 5 ÷ 0.4 = ? – 24 × 2.4
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
18 × 15 + 86 – 58 =? + 38
√(24²+285-8²-172) = ?²
