The smallest of the 3 interior angles of the triangle is 10 degrees. Note that the diagram is not to scale.

Thus, sin 10 degrees = opp / hyp = 200 m / x

0.1736 = (200 m) / x, or x = (200 m) / 0.1736

= 1152 m (rounded up from 1151.75 m).

Jordan bikes at a speed of 8 2/3mph. How many miles will he bike in:<br> 45 minutes?

olganol [36]

Answer:

6 miles

Step-by-step explanation:

You Can make a proportion

$\frac{26/3 miles}{60 minutes}$ = $\frac{x}{45 minutes}$

Now cross multiply

45*26/3 is 360

and 60*x is 60x

make an equation

60x=360

x=6

So 6 miles
