After some snacks at McDonalds at Lower Bonifacio Street, Kristina drove 145 meters towards the three-way junction and turns rig

vaieri [72.5K]

Answer:

125 m

Step-by-step explanation:

The path of Kristina is in the shape of a right triangle where, the perpendicular is the path from the McDonalds to the three-way junction which is 145 m and the shortest distance between the McDonalds and the church is 191.442 m.

By Pythagoras theorem

$145^2+x^2=191.442^2\\\Rightarrow x=\sqrt{191.442^2-145^2}\\\Rightarrow x=125\ \text{m}$

Christina had to travel 125 m from the three-way junction to the church.

Tanya [424]

Answer:

The first one

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan30° = $\frac{opposite}{adjacent}$ = $\frac{AC}{BC}$ = $\frac{b}{8}$
