In the diagram. Find h
Answer Details
A△ △ = √S(S−a)(S−b)(S−c) S ( S − a ) ( S − b ) ( S − c ) (Hero's Formula)
S = a+b+c2 a + b + c 2 = 5+6+72 5 + 6 + 7 2
182=9 18 2 = 9
A△ △ √9×4×3×2 9 × 4 × 3 × 2
√216=6√6cm3 216 = 6 6 c m 3
A△ △ = 12×6×h 1 2 × 6 × h
6√6=12×7×h 6 = 1 2 × 7 × h
h = 12h√6
Given that for sets A and B, in a universal set E, \(A \subseteq B\) then \(A \cap (A \cap B)^{1}\) is
Evaluate \( \frac{1}{3} \div \left[\frac{5}{7}\left(\frac{9}{10}-1+\frac{3}{4}\right)\right] \)
Evaluate \( \frac{0.36 \times 5.4 \times 0.63}{4.2 \times 9.0 \times 2.4} \)
Without using table, solve the equation \(8x^{-2} = \frac{2}{25}\)
Solve for x if 25x + 3(5x) = 4
Evaluate \( \frac{\log_{5}(0.04)}{\log_{3}18-\log_{3}2} \)
Given that \( \sqrt{2} = 1.1414 \), find without using tables, the value of \( \frac{1}{\sqrt{2}} \)
Simplify \( \sqrt{48} - \frac{9}{\sqrt{3}} + \sqrt{75} \)
