Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
Answer:
1000 times
Step-by-step explanation:
To find out how many times 0.1 can fit into 100, we can just divide 100 by 0.1.
But, we first find out how many times can 1 fit into 100.
No. of times 1 fit into 100 = 100 / 1 = 100 times
Now we know 1 is 10 times of 0.1, so we multiply the above by 10,
so 100 * 10 = 1000 times.
Therefore 0.1 can fit into 100 a 1000 times.
4/9m=slope
it has no y intercept so it passes through the origin
4/9m=same slope
4/9+1= a parallel line to this
