Question
A tree stands tall with a height of 54 meters. From a
point 'x' meters away from its base, the angle of elevation to the top of the tree is 60Β°. Determine the value of 'x'.Solution
In the given figure, let points 'A' and 'B' represent the top of the tree and the base of the tree, respectively and let 'C' represents the point on the ground that is 'x' metres away from the base of the tree (BC = x).In right triangle ABCtan 60oΒ = (AB/x)Or, (54/x) = β3So, x = 54 Γ· β3 = 18β3 metres
- Find the value of the expression:
40 + 5 β 7 Γ [16 + 9 β 3 Γ (27 β 13)] 8 Γ (25 % of 720) β 50 % of 135 % of 840 = ?
- What will be come in place of (?) in the given expressions.
(3/4 of 480) β (2/5 of 350) = ? - What will come in place of (?), in the given expression.
β2025 + 35% of 400 = ? 13/3 β (23/6) = ? β (22/9)
(1296)Β -3/4Β = ?
- What will come in the place of question mark (?) in the given expression?
?Β² = 28% of 35% of 4500 What will come in the place of question mark (?) in the given expression?
(72 Γ 6 Γ· 12) Γ 6 = ?
What will come in the place of question mark (?) in the given expression?
? = 70% of 36% of (25 Γ 320) + 150
