Question

me podrían ayudar en esta plis :(​

Answer 1

Explicación paso a paso:

1.

Z = 13

Tanx = 12/5

Secx = 13/5

2.

TanA = 2/5

2² + 5² = h²

29 = h²

√29 = h

SenA = 2/√29

CscA = √29/2

3.

Senx = 3/4

3² + y² = 4²

y² = 7

y = √7

Cotx = √7/3

4.

Cosx = 1/2

1² + a² = 2²

a² = 3

a = √3

Cscx = 2/√3 = (2√3)/3
