Answer: The answer is option C: 10cm, 6cm and 8cm
Step-by-step explanation: A right angled triangle has an hypotenuse (the longest of all three sides) facing the 90 degree angle. Also a right angled triangle can be solved by means of the Pythagoras theorem which states that;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse (10cm) and AB (6cm) and BC (10cm) are the other two sides.
If that is the case, we can insert the values as given in option C to know whether or not they make up a right angled triangle. Therefore
10^2 = 6^2 + 8^2
100 = 36 + 64
100 = 100
Therefore the side lengths 10cm, 6cm and 8cm satisfies the requirements for a right angled triangle
Answer:
yes you may use the answer will be 100% correct
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be: 
and twice this sum would be: 
Thus, "twice the sum of y and 9" is:
Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to.
For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.
The solution on that is 7
