Question
If cot5A = tan(3A-14˚), find the value of A? Given that
5A and 3A-14˚ are acute angles.Solution
Always remember that cot & tan are compliment to each other So tan ɵ = cot( 90-ɵ) So it is given that cot5A = tan(3A-14˚) Hence 5A + 3A - 14˚= 90˚ So 8A - 14˚ = 90˚ or 8A = 90˚+14˚=104˚ or A = `104^@/8` = 13˚
(804/65) ÷ (11/798) × (129/131) = ?
1254.04 – 440.18 + 399.98 ÷ 10.06 = ?
( 19.95% of 799.89 ) × 12.05 = ? 2 + 18.99 × 6250 ÷ 1250
