Sagot :

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
