Answer:

$\tt B)\;93^o$

Step-by-step explanation:

$\tt 2(19x+1)+(19x+1)+15x=360$

$\tt 38x+2+19x-2+15x=360$

$\tt 38x+19x+15x+2-2=360$ (Add similar elements)

$\tt 72x+2-2=360$ (2-2=0)

$\tt 72x=360$

$\tt \cfrac{72x}{72}=\cfrac{360}{72}$ ( Divide both sides by 72)

$\tt x=5$

Now,

m∠km:-

$\tt 19x-2$

$\tt 19(5)-2$ (Multiply 19*5= 95)

$\tt =95-2$ (Subtract)

$\tt = 93$

Therefore, m∠km=93° is the answer.

Answer:

45 miles

Step-by-step explanation:

Use the Pythagorean Theorem. Imagine a line connecting the ends of the right angle you made by driving. It would make a right triangle. You are trying to find the hypotenuse. Use the formula $a^{2} +b^{2} =c^{2}$ . Square 27, or multiply 27 by 27, to get 729. Add this to the square of 36, 1296. So $c^{2}$ = 2025. Find the square root of 2025. $\sqrt{2025}$ = 45.
