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

Answer: 73.55%
Step-by-step explanation:
p = (100-a) e^-b(0.07)
we have a = 20 and b =1.2
= (100-20) e^-(1.2)(0.07)
= 80(e^-0.084)
= 80(0.919431)
= 73.55%
Answer:
m∠BFE = m∠BAF + m∠AFE
m∠BFE = 65º + 25º
m∠BFE = 90º
m∠AFC = m∠AFB + m∠BFC
m∠AFC = 65º + 45º
m∠AFC = 110º
m∠BFD = m∠BFC + m∠CFD
m∠BFD = 45º + 70º
m∠BFD = 115º
