True: The trigonometric ratios sine and secant are reciprocals of each other

That's FALSE.

It's sine and cosecant that are reciprocals, as are cosine and secant, as well as tangent and cotangent.

The "co" or complementary functions are their corresponding non-complementary function applied to the complementary angle: cos(x) = sin(90-x), that kind of thing.

The non-co functions sine, secant and tangent all increase with increasing angle in the first quadrant. The co functions all decrease.

Since when sine increases its reciprocal decreases, its reciprocal must be one of the co functions, and of course it's cosecant.

Figure ABCD is a parallelogram. What is the value of n?

Zigmanuir [339]

Answer

Find out the what is the value of n.

To prove

By using the parallelogram property .

In parallelogram opposite angels are congruent .

As shown in the figure .

∠B = ∠ D

As given

∠B = (2n + 32)°

∠D = (4n - 2)°

(2n + 32) = (4n - 2)

solving the above

4n -2n = 32 +2

2n = 34

$n = \frac{34}{2}$

n = 17

Therefore the value of n is 17 .

Use the commutative property to simplify the expression 4/3 + 3/4 + 2/3

saw5 [17]

The simplified expression using the commutative property is : $\frac{6}{3}$ + $\frac{3}{4}$

<h3>Meaning of commutative property</h3>

commutative property can be defined as a mathematics attribute that is possessed by a mathematical equation, that enables the objects undergoing addition or multiplication to change position.

In conclusion, The simplified expression using the commutative property is : $\frac{6}{3}$ + $\frac{3}{4}$

<h3>Analysis</h3>

4/3 + 3/4 + 2/3 = ( $\frac{4}{3}$ + $\frac{2}{3}$ ) + $\frac{3}{4}$ = $\frac{6}{3}$ + $\frac{3}{4}$
