Prove that : 1/1-secA + 1/1+secA = -2cot^2A

irina1246 [14]

Answer:

Step-by-step explanation:

LHS = 1/1-secA + 1/1+secA

$= \frac{1*(1+Sec A)}{(1-Sec A)(1+Sec A)}+\frac{1*(1-Sec A)}{(1+Sec A)*(1-Sec A)}\\\\=\frac{(1+Sec A)}{1-Sec^{2} A}+\frac{(1-Sec A)}{1-Sec^{2} A}\\\\=\frac{1+Sec A+1-Sec A}{(1-Sec^{2} A)}\\\\= \frac{2}{(1-Sec^{2} A)}\\\\=\frac{2}{-(Sec^{2} A - 1)}\\\\= \frac{-2}{Tan^{2} A}\\\\= -2Cot^{2} A$

REY [17]

Answer:

B. 14.34

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between the side opposite the angle of interest and the hypotenuse:

Sin = Opposite/Hypotenuse

For the given triangle, this means ...

sin(35°) = b/25

b = 25·sin(35°)

b ≈ 14.34

How do find the volume of l blocks

kow [346]

For number 1)

you must first split the figure, so subtract the 8 mm from 12 mm to find the width.... = 4mm

so you use the numbers 10 x 2 x 4 = 80 mm

and 2 x 8 x 3 = 48 mm

80 mm + 48 mm = volume of the figure
