Question

Calcula R
R=6√3 sen60°

Answer 1

Respuesta:

a. sen45 + sen60 = √2/2 + √3/2 = (√2 + √3)/2

b. sen30 + cos60 = 1/2 + 1/2 = 1

c.  tan45 - (cos60 + sen30) = 1 - (1/2 + 1/2) = 1 - 1 = 0

d. tan30 × tan60 × tan45 = √3/3 × √3 × 1 = 3/3 = 1

e.  sen45 + 1/2 cos45 = √2/2 + 1/2 · √2/2 = √2/2 + √2/4 = 3√2/4

f. 3cos60 - 2sen30 = 3 · 1/2 - 2 · 1/2 = 3/2 - 1 = 1/2

g. (tan30 + tan60)/(1 + tan30 · tan60) = (√3/3 +√3)/(1 + √3/3 · √3)

= (4√3/3)/2 = 2√3/3
