Arlecino [84]3 years ago
8 0
H= -1 here's why:

7 = 12 + 5h 

First you subtract 12 from both sides then the equation would look like:

-5 = 5h

Then you would divide the equation by 5 from both sides it would then look like:

-1 = h

You start driving north for 24 miles, turn right, and drive east for another 10 miles. At the end of driving, what is your strai
yawa3891 [41]

Answer:

26 miles

Step-by-step explanation:

Given: 24 miles drive to north.

          10 miles drive to east.

Driving pattern form a right angle triangle, which has three leg including straight line distance from starting point (hypotenous).

Now, using Pythogorean theoram to find straight line distance from starting point.

h²= a²+b²

Where, h is hypotenous

            a is opposite leg

            b is adjacent leg.

⇒h²= 24^{2} + 10^{2}

⇒h^{2} = 576+100

⇒h^{2} = 676

Taking square root on both side, remember; √a²= ±a

⇒h=\sqrt{676}

∴ h= \pm 26

Ignoring -26 as distance cannot be negative.

Hence, 26 miles is the straight line distance from starting point.
