Answer:

12/15 acres of land

Step-by-step explanation:

Total measure of land = 2 2/5acres

Total brothers = 3

Amount of acres each brothers will receive = Total measure of land/Total brother

Amount of acres each brothers will receive = (2 2/5)/3

Amount of acres each brothers will receive = 2 2/5 ÷ 3

Amount of acres each brothers will receive = 12/5 ÷ 3

Amount of acres each brothers will receive = 12/5 * 1/3

Amount of acres each brothers will receive = 12/15

Hence each brother will receive 12/15 acres of land

If a cot α = 1 and b cos α = 1, find a2 – b 2

S_A_V [24]

The equivalent expression of the different of two square is -1

Given the following expressions

a cot α = 1

a = 1/cot α = sinα/cosα

b = 1/cos α

We are to find the expression a² - b²

According to difference of two squares;

a² - b² = (a + b) (a - b)

Substitute the given expressions into the formula as shown:

$a^2 - b^2 = (\frac{sin \alpha}{cos \alpha} )^2 - (\frac{1}{cos \alpha} )^2\\a^2 - b^2=\frac{sin^2 \alpha}{cos^2 \alpha} -\frac{1}{cos ^2 \alpha}\\a^2 - b^2=\frac{sin^2 \alpha-1}{cos^2\alpha}\\a^2 - b^2=\frac{-(1-sin^2\alpha)}{cos^2\alpha} \\a^2 - b^2=\frac{-os^2 \alpha}{cos^2 \alpha}\\a^2 - b^2 = -1$

This shows that the equivalent expression of the difference of two squares is -1
