1.
AB:
a² + b² = c²
'a' and 'b' are legs, while 'c' is the hypotenuse
3.6² + 5.2² = 12.96 + 27.04
c² = 40
c = √40
c ≈ 6.3
m∠A:
sine, cosine, tangent
soh - [tex]\frac{opposite}{hypotenuse}[/tex]
cah - [tex]\frac{adjacent}{hypotenuse}[/tex]
toa - [tex]\frac{opposite}{adjacent}[/tex]
∠a:
5.2 = opposite
6.3 = hypotenuse
[tex]\frac{5.2}{6.3}[/tex] = 0.825396...
x = sin^-1(0.825396)
x = 55.6 ≈ 56º
∠b:
90º + 56º = 146
180 - 146 = 34º
