There are 7 girls and 9 boys on a playground.

Anon25 [30]

The ratio of the number of girls to the total number of children is 7 : 16.

<h3>Ratio is defined as follows:</h3>

It is a comparison between two or more numbers that measures sizes in relation to each other
It describe how much of a thing is compared to another.

The number of girls in the playground = 7

The number of boys in the playground = 9

The total number in the playground is the sum of the number of girls and the number of boys.

Therefore,

total children in the playground = 7 + 9 = 16

The ratio of the number of girls to the total number of children can be express as follows:

Ratio = 7 : 16

True or false: the equation tan^2x+1=sec^2x

zhenek [66]

ANSWER

True

EXPLANATION

The given trigonometric equation is:

${ \tan}^{2} x + 1 = { \sec}^{2} x$

We take the LHS and simplify to arrive at the RHS.

${ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x}{{ \cos}^{2} x} + 1$

Collect LCM on the right hand side to get;

${ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x + {\cos}^{2} x}{{ \cos}^{2} x}$

This implies that

${ \tan}^{2} x + 1 = \frac{1}{{ \cos}^{2} x} .$

${ \tan}^{2} x + 1 = {( \frac{1}{ \cos(x) }) }^{2}$

${ \tan}^{2} x + 1 = { \sec}^{2} x$

This identity has been verified .Therefore the correct answer is true.

Answer:

see consider there are three angle 80 and x and 45(the measure of line is 180 so subtract 180 by 125 u will get 45) now measure of angle is 180 soo the value of x is 55degree so value of x is equal to that of z therefore value of z also 55 degree
