How do i find he value of x and the tangent, cosine, and sine of the marked angle?

x = 4, angle of sinθ,cosθ,tanθ are 29.7°

Step-by-step explanation:

Using Pythogaras' Theorem:

x² = (√65)²-7²

= 16

x = √16

= 4

sinθ = opposite/hypotenuse

θ = 4/√65

θ = sin^-1(4/√65)

θ = 29.7°

cos θ = adjacent/hypo

θ = 7/√65

θ = cos^-1(7/√65)

θ = 29.7°

tan θ = oppo/adj

θ = 4/7

θ = tan^-1(4/7)

θ = 29.7°

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
