+89 Find the areas of the following triangles. Round to the nearest hundredth:
a) a=3, b=6, C=35°
b) a=5, b=11, c=7
+23246 If you know SAS, use this formula: Area = a·b·sin(C)
where a and b are a pair of sides and angle(C) is the included angle.
For this problem: Area = 3 · 6 · sin(35o) =
If you know SSS, use Heron's formula: Area = sqrt( s · (s - a) · (s - b) · (s - c) )
where s is the semiperimeter: s = (a + b + c) / 2
Place the numbers into these two formulas ...
