Find the value of x, given cos 0 = 0.4<br><br><br><br> PLEASE HELP!!!!!! And explain if possible

elena-14-01-66 [18.8K]

Answer:

$x=30$

Step-by-step explanation:

For each right-angled triangle:

$\cos\theta=\frac{cathetus \ adjacent \ \theta}{hypotenuse}$

Because $\cos \theta=0.4, \ \ cathetus\ adjacent \ \theta \ = \ 12, \ \ \ hypotenuse=x$

we have an equation

$0.4=\frac{12}x$

multiplying both sides by x, we get $0.4x=12$

dividing both sides by 0.4 and $x=\frac{12}{0.4}$

using calculator, we divide 12 by 0.4

and finally x=30

Find the value of x L 7x-7 M 4x+14

viktelen [127]

Answer:

x= 7 sorry if I'm wrong:(

Step-by-step explanation:

7x - 7 = 4x + 14

7x - 7 - 4x = 4x + 14 - 4x

3x - 7 = 14

3x - 7 + 7 = 14 + 7

3x = 21

x = 21/3

x = 7
