Answer 1

AnswerS:

Let A be the surface area, b the base, h the height;

h₁=8.4 cm

h₂=7.8 cm

b= 9 cm

A= 3(1/2bh₁)+1/2 bh₂

A=3(1/2(9)(8.4))+1/2 (9)(7.8)

A= 148.5 cm³

Answer:

Step-by-step explanation:

The figure given above is a square pyramid, having a square base and 4 triangular faces on the sides that are of the same dimensions.

Surface area of the square pyramid is given as:  

Where,

B.A = Base Area of the pyramid = 9*9 = 81 in²

P = perimeter of the base = 4(9) = 36 in

L = slant height of pyramid = 9.2 in

Plug in the values into the given formula to find the surface are

Answers

Answer:

72= 36 + 2x

Step-by-step explanation:

1 shot= $12

  3 shots= $12×3= $36

$72-$36= $36

2 pills= $36

QRS~TUV. what is the measure of V?

Answers

Answer:

70°

Step-by-step explanation:

As we can see that that triangles are similar so

angles are equal

< U = 47° and < T = 63°

So now

< U +< T + <V = 180°< being sum of angles of triangle >

47° + 63° + < V = 180°

< V = 180° - 110°

< V = 70°

Hope it will help :)❤

Answer:

70 degrees

Step-by-step explanation:

Similar triangles are different in size, but same in angles. That means...

Angle R is congruent to Angle U, Angle Q is congruent to Angle T.

By the Triangle Sum Theorem, all triangles add to 180 degrees.

Angle U + Angle T + Angle V = 180 degrees

47 + 63 + Angle V = 180

Angle V = 70
