Answer:
Step-by-step explanation:
Sin = opposite/hypotenuse
SinA = 5/13
Sin B = 12/13
Cos = adjacent/hypotenuse
Cos A= 12/13
Cos B = 5/13
tan = opposite/adjacent
tan A = 5/12
tan B = 12/5
m A = 23 degrees
m B = 67 degrees
Exercise 3
a = 0.0523
b = 0.1045
c = 1
Exercise 4
a 35 degrees
b 47 degrees
c 44 degrees
Exercise 5
1) x^2 + x^2 = 200
2x^2 = 200
x^2 = 100
x = 10
2) I can‘t see the measure of the given side
