Answer:
I'm guessing that makes obtuse triangle
why don't you try draw the triangle
Acute triangle : 0<x<90 degrees
right triangle : x=90 degrees
obtuse triangle :triangles that angles are bigger than 90 but smaller than 180 degrees
reflex angle:bigger than 180 but smaller than 360 degrees
Answer:
75 degrees
Step-by-step explanation:
those two angles = 180
180-105 =75
Answer:
The ride lasts 10 minutes.
Step-by-step explanation:
The triangle that is formed is attached.
In order to find out how long the ride lasts, we need to figure out the horizontal distance 
From trigonometry we have:
Therefore
Now the amount of time 
the gondola ride lasts is equal to the distance 
divided by the speed of the gondola:
To the nearest minute this is 10 minutes.
