The closest estimate is 108.

The volume of a triangular prism is found using the formula

V = 1/2*b*h*H, where b is the base of the triangle, h is the height of the triangle, and H is the height of the prism.  With our information we have:

V=1/2(12.6)(1.6)(10.75) = 108.36.

A 92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St
ohaa [14]

Answer:

41.802 feet

Step-by-step explanation:

Given that a  92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St.

We can visualize a triangle formed by the three streets One side is 92 feet.

Angle opposite 92 feet = 180-68-34 = 78

Let x be length of Cove st and y length of Mateo st.

Using sine angle for triangles,

\frac{92}{sin 78} =\frac{x}{sin 34} =\frac{y}{sin 68}

Simplify to get

x=52.595

y=87.207

Distance saved= x+y-92\\= 139.802-92\\=41.802

Plzzzzz help I’ll mark brainlest thxxxx
Sloan [31]

an = a1 +d(n-1)

a4 =a1+d(4-1)

-4 = -1+d(3)

add 1 to each side

-3 = 3d

d= -1

an = a1 +d(n-1)

an = -1 +-1 (n-1)

an = -1 -n +1

an = -n
