Answer:

k = 26

Step-by-step explanation:

90 + 8 = x + k

x = 72

90 + 8 = 72 + k

90 + 8 = 98

98 = 72 + k

98 = 72 + k

-72    -72

98 - 72 = 26

72 + k - 72 = k

26 = k

k = 26

Answer:

k=26

Step-by-step explanation:

90+8=x+k

<=>98=x+k

<=>98=72+k (Because x=72)

<=> k=26

So k=26

Rasek [7]

Answer:

A  40

Step-by-step explanation:

We can find angle K

J + K + L = 180  The angles of a triangle add to 180

50 + K + 90 =180

140 +K = 180

Subtract 140 from each side

140-140 + K = 180-140

K = 40

Since the triangles are congruent

J = P

K = N

L = M

We want to find N

K = N = 40

K = N

Make a factor tree for 16
jonny [76]
         16
          ∧
     4   X  4
      ∧      ∧
   2 X 2   2 X 2

The answer is 2 x 2 x 2 x 2 or 2⁴   This would have worked as well had you broken 

down 16 into 8 x 2.  You would get the same answer as the 8 would break down into 4 x 2 and the 4 would break down into 2 x 2.

polet [3.4K]

Answer:

see below

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We can find the radius from the diameter

r = d/2 = 34/2 = 17

V = (3.14) (17)^2 * 27

V =24501.42 m^3

The surface of a cone is found by

SA = pi r^2 + pi r  l where l is the slant height

We can find the radius from the diameter

r = 8/2 = 4

SA =(3.14) * 4^2 + 3.14 * 4*7

      =50.24+87.92

        138.16 in^2

The lateral surface area of a pyramid is found by taking the area of the sides

LSA = 4 * the area of a triangle

          we multiply by 4 since there are 4 sides

        = 4 * 1/2 b*h  where b is the base of the triangle and h is the height of the triangle.  (in this case it would be the slant height)

           = 2 * 8 *22

          =352 m^2
