Question

Por favor me ajude!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

7- tg=cat op / cat ad
tg=3/4

8- sen30=cat op / hip
1/2=x/10
x=5

1/2=y/6
y=3

10- hip^2=12^2+16^2
hip=√144+256= √400 = 20

a) senA= 16/20 = 4/5
b) cosA= 12/20 = 3/5
c) tgA= 16/12 = 4/3
d) senB= 12/20 = 3/5
e) cosB= 16/20 = 4/5
f) tgB= 12/16 = 3/4
