50 in, 48in, 14in, should create a right triangle.
Answer:
X = 4
Step-by-step explanation:
That traingle is an isosceles triangle. You know this because the base angles, 45 and 45 are the same. Another characteristic of an iscosceles traingle is that the base sides ( in this case 4 and X ) are always the same
If you are looking for the sum of two consecutive integers, there is a quick way to get the answers. Divide the number by two and you will find your answers.
249/2 = 124.5
Your two consecutive numbers are 124 and 125.
124 + 125 = 249.
If you mean by the square root of 249, your answers are 15 and 16; 15^2 = 225, 16^2 = 256.
I hope this helps!
Answer:
ab = 1/2.
Step-by-step explanation:
The sides of the large square have length √5 while the sides of the small one have sides of length 2.
Each corner has a right triangle with legs of length a and b and hypotenuse 2.
So we have the system
a + b = √5
a^2 + b^2 = 2^2 = 4
Using the identity a^2 + b^2 = (a + b)^2 - 2ab:
4 = (√5)^2 - 2ab
4 = 5 - 2ab
2ab = 5 - 4 = 1
ab = 1/2.
