Answer:

x = $8\sqrt{3}$

y = $4\sqrt{3}$

Step-by-step explanation:

• tan 60° = 12/ y [tan θ = opposite/ adjacent]

y = 12/ tan 60°

y = $4\sqrt{3}$

• x² = y² + 12² [Pythagoras's theorem]

x² = ( $4\sqrt{3}$ )² + 144

x = $\sqrt{(4\sqrt{3})^{2} \space\ + \space\ 144}$

x = $8\sqrt{3}$

Th temperature at 6 pm was 72f. This temperature was 8F less than 4pm. The temperature at 10am. Was 5F greater than the 4pm temp

DanielleElmas [232]

Temp. at 6 pm. was 72...
that temp. was 8 less then at 4 pm....so at 4 pm, it was 72 + 8 = 80
the temp. at 10 am was 5 greater then at 4 pm.....so at 10 am, it was 80 + 5 = 85 F <===

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of

KiRa [710]

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

$\frac{L}{W}=\frac{5}{3}$

Where:

L represents the new length
W represents the new width

Now, we know that each dimension is reduced by x inches, it means:

$L=18-x$

$W=12-x$

Then, we will have:

$\frac{18-x}{12-x}=\frac{5}{3}$

Finally, we just need to solve it for x.

$3(18-x)=5(12-x)$

$5x-3x=60-54$

$2x=6$

$x=3$

<u>Therefore, the value of </u><u>x = 3.</u>

Jaxon and Isaac live different directions from the city center. Jaxon lives 10 blocks east and 5 blocks north. Isaac lives 8 blo

givi [52]

Answer:

Step-by-step explanation:

As shown in the figure attached Jaxon is 10 blocks east and 5 blocks north.

So x-coordinates of Jaxon will be 10 units and y-coordinates will be 5 units.

and coordinates will be (10,5)

Similarly coordinates of Isaac will be defined by his distance towards west and distance towards south.

So x-coordinates will be 8 units and y-coordinates will be 15 units.

Therefore, coordinates of Isaac will be (-8,-15).
