You are building a house and are making a drawing of the kitchen. the sink is 3 feet away from the dishwasher, and the sink is 8
Natasha_Volkova [10]

Consider the triangle with vertices S (sink), D (dishwasher) and F (fridge). From the conditions data SD=3, SF=8 and ∠S=48°.

Use the cosine theorem to find unknown distance:

FD^2=SD^2+SF^2-2SD\cdot SF\cdot \cos S,

FD^2=3^2+8^2-2\cdot 3\cdot 8\cdot \cos 48^{\circ},\\ FD^2=9+64-48\cdot 0.67,\\ FD^2=40.84, \\ FD=\sqrt{40.84}, \\  FD=6.39 feet.

Then the distance between dishwasher and fridge is 6.39 feet.

Are these dimensions reasonable is up to kitchen owner))

$45.

When the TV is bought on hire purchase, you deposit $35 and pay $30 monthly. There are 12 payments. 12 * 30 = $360. 360 + 35 = $395.

Since cash would've cost $350, the amount of money saved by paying cash is 395 - 350 = $45.

Hope this helps!
