It is 45° because the sum of all the angles of a triangle is 180° so
Answer:
3%
Step-by-step explanation:
13 is 25% of 52. If Mickey´s first diamond is aimed to be drawn on the 8th draw, then you need to divide 25% by 8.
This would result in 3.125%
X should also be 50° because they are corresponding angles.
Answer:
The greatest common factor of 15 and 31 is 1.
Step-by-step explanation:
What are the factors of 15?
1, 15 and 3, 5
What are the factors of 31?
31 and 1
We can see that 31 and 15 only share on common factor, which is 1.
1 is the greatest and the only factor!
Call the length a, the width b
Perimeter = (a+b) x 2
We have : a - b = 4 and (a+b) x 2 = 56
-> a + b = 28
-> a - b = 4
=> a+b + (a-b) = 32
2a = 32
a = 16
b = 56:2-16 = 12
So, the length = 16 and the width = 12
