Answer:
the answer is 1 2/3 - 1 3/7 ÷ (1/2+ 4/7) = 2/9
Answer:
720 degrees.
Step-by-step explanation:
The sum of the interior angles of a convex polygon with n sides is
180(n - 2) degrees.
In this case, n = 6 sides, so the angle sum is
180(6 - 2) = 180(4) = 720 degrees.
The reason this works is that if you draw a diagonal from one vertex to the others (see attached image), you get 2 fewer triangles than the number of sides. Each triangle contains a total of 180 degrees, so the total of all the interior angles is 180(n - 2).
Answer:
<h2>45 in²</h2>
Step-by-step explanation:
Formula:
area of a parallelogram = base × height
==================================
By reading the figure :
base = 15
height = 3
Therefore,
The area of the parallelogram = 15 × 3
= 45
Answer:
Turn off battery supply → The electromagnet turns off.
Place a magnet care inside the coil of wire → The strength of the electromagnet increases.
Change the direction in which the current flows → The poles of the electromagnet reverses
