Answer:

28.

Step-by-step explanation:

1) the range of x is: 2x-7>0; ⇔ x>3.5.

2) the solution is:

$\sqrt{2x-7}=7;$

2x-7=49;

2x=56; ⇔ x=28 (28>3.5, belongs to the range of x above).

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

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
