quester [9]

We all know that a triangle has 180 degrees.
3x-8+5x-6+4x+2=180
12x-12=180
12x=180+12
12x=192
x=16.

∠A=2(16)+8=40
∠B= 90-16=74
∠C = 5(16) -14= 66

Newberg is 8 kilometers due north of the airport, and summer field is 15 kilometers due east of the airport. How far apart are n

Karo-lina-s [1.5K]

Answer:

The correct answer is 17 kilometers.

Step-by-step explanation:

Let A denote the point where the airport is located.

Newberg is located 8 kilometers due north of airport say at point B.

Summer field is located 15 kilometers due east of the airport say at point C.

Thus ABC is the required right angled triangle with sides AB = 8; AC = 15; and ∠A = 90°.

Thus we use Pythagoras theorem to find the value of the side BC which indeed would give us the distance between Newberg and Summer field.

∴ $BC = \sqrt[2]{ AC^{2} + AB^{2} }$ = $\sqrt[2]{ 15 ^{2} + 8^{2}}$ = $\sqrt[2]{289}$ = 17 kilometers.

Thus the distance between Newberg and Summer field is 17 Kilometers.

I don't know where you got those answers, but the actual equation that represents those points is: y = -1/2x + 11. None of those listed above are correct.

How do you turn -8/9 into a decimal and percent?

monitta

You need to divide the numerator by the denominator so it should be 8 divided by 9 to turn it into a percent multiply the decimal you get by 100. Hope this helps!
