Angle K = angle M

(4x-1)=(2x+27)

4x-2x=27+1

2x=28

x=14

K=4x-1 then 4(14)-1
55 degrees
M=2x+27 then 2(14) +27
55 degrees
K+M+L =180
55+55+L=180
110+L=180
L=70 degrees
Therefore K=55 degrees M=55 degrees L=70 degrees

6/7 divided by 12/14 please show the work
Minchanka [31]

Answer:

1

Step-by-step explanation:

When dividing one fraction by another, the best way to solve it is to multiply by the reciprocal. The reciprocal just flipping the fraction over. So you would leave the 6/7 and the multiply by 14/12( because you are multiplying by the reciprocal). When you do that, you then can just multiply the top and the bottom to form one fraction. The numerator is 6*14 = 84, and the denominator is 7*14 = 84. So you are left with 84/84 which anything over itself is equal to one.

Hope this helps!

Is this multiplication? Can you also help me with the answer!?
vredina [299]

Answer:

84,375 m^2

Step-by-step explanation:

We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).

Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.

Area of a square is length times width.

Total area = 4\times(\frac{1}{2}\times 225 \times 75)+225\times225 = 84375 m^2
