In general, units conversion is done by multiplying by a factor whose numerator and denominator have equal values, but different units. The units in that fraction need to be arranged to cancel the units you don't want and leave the units you do want.

If tanx-cotx=5 then what is the value of tan²x+cot²x

Roman55 [17]

Answer:

27

Step-by-step explanation:

note that tanx cotx = tanx × $\frac{1}{tanx}$ = 1

Given

tanx - cotx = 5 ( square both sides )

(tanx - cotx)² = 5² = 25 ← expand left side using FOIL

tan²x - 2tanxcotx + cot²x = 25

tan²x - 2 + cot²x = 25 ( add 2 to both sides )

tan²x + cot²x = 27

Answer:

$\displaystyle 40\:mm.^2 = A \\ 32\:mm. = P$

Step-by-step explanation:

All vertices meet at right angles, so sealing off these two rectangles will give you this:

$\displaystyle [2][4] + [4][8] = 8 + 32 = 40; 40mm.^2 \\ 4 + 6 + 2 + 4 + 8 + 8 = 32; 32mm.$

* The missing sides are 4 and 6.

I am joyous to assist you anytime.
