The equation cos−1 = x can be used to determine the measure of angle BAC.

Sergio [31]

we know that

in the right triangle ABC

the value of cosine of angle x is equal to

$cos(x)=\frac{AC}{AB}$

we have

$AC=3.4\ cm\\AB=10\ cm$

substitute the values

$cos(x)=\frac{3.4}{10}=0.34$

Find the measure of angle x

$x=cos(x)^{-1} =arc\ cos(0.34)=70.12\°$

Round to the nearest whole degree

$x=70\°$

therefore

the answer is

$70\°$

Find the value of x that will make A||B. 5x + 9 A B 6x-2 X = [?] Enter

givi [52]

Answer:

$x = 11$

Step-by-step explanation:

Given

Parallel lines A and B

Required

Find x

For A and B to be parallel, then 5x + 9 and 6x - 2 are alternate interior angles

And alternate interior angles are always equal

This means that

$5x + 9 = 6x - 2$

Collect like terms

$5x - 6x = -2 -9$

$-x = -11$

Multiply both sides by -1

$-1 * -x = -11 * -1$

$x = 11$
