Answer:

120 minutes or 2 hours

Step-by-step explanation:

We know that it takes a car 30 minutes to travel 45 km so

30 m : 45 km

?  m : 180 km

180 ÷ 45 = 4

30 × 4 = 120

45km : 30 min = 180km : x

x = \frac{180*30}{45} = \frac{180*2}{3} = 60*2 min = 120 min = 2h

Find the length of the missing side. The triangle is not drawn to scale.
suter [353]

Answer:

D.) 8

Step-by-step explanation:

You can use the Pythagorean theorem because this is a right triangle:

a^2+b^2=c^2

a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it  is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.

Fill in values:

a^2+15^2=17^2

Simplify exponents:

a^2+225=289

Isolate the variable. Subtract 225 from both sides:

a^2+225-225=289-225\\a^2=64

Find the square root of both sides:

\sqrt{a^2}=\sqrt{64}\\  a=8

The missing leg length is 8.
