x ≠ 90
180:(x-90)=105
180=105(x-90)
180=105x-9450
-105x=-9630
-105x:(-105)=-9630:(-105)
x=9630/105
x=91,7

A lot of us just can't live without our gadgets. In fact, we are so caught up
in texting, tweeting, surfing and updating our Facebook statuses that we
are unaware of what is happening in the world around us. Although
gadgets are very useful, sometimes they can get us into trouble.

I've had a few awkward moments while using some gadgets. 1
Last year we went to London. My dad bought a GPS receiver so we
could find our way around town easily. One evening I decided to use it
to walk to a restaurant with my parents. Everyone followed
me eagerly. But after walking half an hour we found ourselves at the
same spot. I was puzzled. Suddenly my sister pointed across the
square. There was the restaurant. Then, we understood. The
GPS receiver was on driving mode and took us through all the one-way
streets to reach the restaurant!

I think the most embarrassing moment I've ever had with a gadget was
with my new smartphone. My dad bought this really cool smartphone
for my birthday. I took it out of its box and started playing
around with it. It has an excellent menu and loads of applications but it
was all new to me then. I was so busy going through the menu when
suddenly I walked smack-bang into someone and their ice cream went
all over me. Everyone around laughed at me standing there like a circus
clown with ice cream all over my face. I had a good laugh
about it with my parents later that day though.
