In a right triangle, θ is an acute angle and cos θ = 4/9. What is the value of tan θ

cos Θ = 4/9. take both sides by the inverse operation of cos.

cos^-1(Θ) = cos^-1(4/9)

Θ = 63.61°

tan(63.61°) = 2.02°

d.) yes, because the volume of the cone is greater than the volume of the sphere

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
