1. In triangle ABC, if <A=50 degrees, a=10 and c=12, find <B, <C and b. Round to
the nearest tenth.
<C=66.8
<B=63.2
<b=11.65
2. 1cm=5km
The distance from City A to City B is 17.5cm
17.5*5=87.5km
For m

2. For the figure, determine whether each statement is true or false. If a statement
is true, explain why.
(a) <1=90 degrees This statement is False.
(b) <1=<5+<11

1. For Triangle ADE (AE=DE)
Therefore angle EAD is equal to angle EDA and Angle AED=105 degrees
So angles EAD and EDA =37.5 degrees;
For Triangle BDE (BD=BE)
Therefore angle BED=BDE=37.5, DEB=ABC=105
