There is triangle one of the angles is 101 degrees and the other is 38 workout x

Wittaler [7]

Angle sum property = Sum of the three angles of a triangle will be equal to 180° .

Using this let us find out the measure of x .

Measure of first angle = 101°

Measure of second angle = 38°

Measure of third angle = x

$101 + 38 + x = 180$

$139 + x = 180$

$x = 180 - 139$

$= x = 41$

$∴ \: the \: value \: of \: x \: = 41°$

From 86 books to 150 books

Mademuasel [1]

150 books-86 books= 64 books.

We originally have 86 books, so the percent of increase is:
64 books/ 86 books* 100%= 74.42%

The percent of increase is 74.42%~

Cos^-1(-x)=-Cos^-1x for -1<x<1 TRUE OR FALSE?

VMariaS [17]

We are given

$cos^{-1}(-x)=-cos^{-1}(x)$

Firstly, we will simplify left side

and we will check whether it is equal to right side

Left side:

Let's assume y left side expression

$y=cos^{-1}(-x)$

now, we can take cos on both sides

$cos(y)=cos(cos^{-1}(-x))$

we can simplify it

$cos(y)=-x$

Right side:

Let's assume y left side expression

$y=-cos^{-1}(x)$

Multiply both sides by -1

$-y=cos^{-1}(x)$

now, we can take cos on both sides

$cos(-y)=cos(cos^{-1}(x))$

we can simplify it

$cos(-y)=x$

$cos(y)=x$

we can see that

both sides cos(y) value is different

so, this is FALSE.........Answer
