Use the given information to find the exact value of each of the following. a. sine 2 thetasin2θ b. cosine 2 thetacos2θ c. tangent 2 thetatan2θ

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
