12,571.4286 you subtract 1000 from the total, and divide by 7.
Answer:
140
Step-by-step explanation:
Angles in a triangle add up 180 :
180 = 107 + 33 + y
y = 180 - (107+33)
y = 180 - 140
y = 40
Angles on a straight line add up to 180 so :
180 = x + y
180 = x + 40
x= 180 - 40
x = 140
Hope this helped and have a good day
Answer:
I think option B is correct
Total number is 40
Percentage asked is 75

= 30
Therefore the correct answer is 30
First we need to find the missing side, use

So the missing leg = the sqrt of the hypotenuse squared minus the other leg squared.
Let's substitute the numbers,

Solve for the squares,

Subtract,

Solve for the root,

~~
So our missing length is 8.
To find the perimeter of the triangle, simply add all the sides....
