260/4 = 65 square inches is area of a side 
area of a side = base*height/2 = base *13/2

65 = b*13/2

130=b*13

b = 10 so the side length equal 10 inches 

area of base = 10*10 = 100 

volume of a pyramid = area of base time height /3 

(the height of pyramid)^2 = 13^2 - 5^2

h^2 = 169 -25 = 144 

h = 12 

V = area of base time height /3 = 100*12/3 = 400 cubic inches 

hope this will help you

Find the exact value of the indicated trigonometric function of θ.
Mariana [72]

Answer:

cosθ = -√(35/36)

tanθ = -1/√35

Step-by-step explanation:

We know that

sin²θ + cos²θ = 1

(1/6)² + cos²θ = 1

1 - (1/6)² = cos²θ

35/36 = cos²θ

sec θ = 1/ cosθ

1/ secθ = cos θ

Because secθ < 0, 1/ secθ would also be < 0, so cos θ < 0

cosθ = -√(35/36)

tanθ = sinθ/cosθ = (1/6)/-√(35/36)

= (1/6) / -(√35/6)

= -1/√35
