The value of x given that the sum of exterior angle is 360 is 27
<h3 /><h3>Sum of exterior angle of a pentagon </h3>
Sum of exterior angle of a pentagon is 360°. Taking the sum of the angles and equating to 360 degrees, we will have:
2x - 20 + 2x + 50 + 3x + 10 + 3x + 50 = 360
Collect the like terms
10x + 90 = 360
Subtract 90 from both sides
10x + 90 - 90 = 360 - 90
10x = 270
x = 27
Hence the value of x given that the sum of exterior angle is 360 is 27

Step-by-step explanation:
Answer:
A, B, F
Step-by-step explanation:
The area of each face is 25 cm
First off all, if we have 1 gram of a substance that has 0.52 gram of copper and 0.26 gram of zinc, the remainder will be:

Since we know that t<span>he remaining portion of the substance is nickel, we have 0.22 gram of nickel.
Now, Ben estimates that 1 gram of the substance has 0.2 gram of nickel. To find how many grams of nickel are in 35 grams of the substance, we are going to multiply the grams of the substance by the gram of nickel:
</span>
We can conclude that according to Ben, 35 grams of the substance has 7 grams of nickel.But we know that in 1 gram of the substance are not 0.2 gram of nickel but 0.22. So lets multiply the grams of the substance by 0.22 to find the actual grams of nickel in it:
We can conclude that 35 grams of the substance has 7.7 grams of nickel. <span>
