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

lana66690 [7]

Answer:

162.1%

Step-by-step explanation:

Given that:

Size of previous living space = 1450 sq ft

Size of new living space = 3800 sq ft

% increase in living space ;

Increase in living space = 3800 - 1450 = 2350 sq feet

(Increase / previous size) * 100%

(2350 / 1450) * 100%

1.6206 * 100%

= 162.06%

= 162.1%
