Answer 1

TG A = 48/14

TG A=3,42

TG E =14/48

TG E = 0,29

2)X ² = 3√2²+3√2²

X²=3*2 + 3*2

X²=6+6

X=√12

X=2√3

B)16²=2²+X²

256=4+X²

X²=256-4

X²=252

X=√252

X=6√7

3) COS 45=X/20√2

2√2=X/20√2

2X=40

X=20

SEN 45=Y/20√2

2/√2=Y√20√2

2Y=40

Y=20

B)SEN 30=X/9√3

1/2=X/9√3

2X=9√3/2

X=9√3/2

COS 30 = Y/9√3

√3/2=Y/9√3

2Y=9√3*√3

2Y=27

Y=27/ 2
