Answer:
AB = 2*sqrt(5) or
AB = 4.47
Step-by-step explanation:
AB is the hypotenuse of a right triangle A and B and the corner where 2 and 4 meet.
The length of AB is governed by the Pythagorean Theorem.
AB^2 = x^2 + y^2 Substitute 2 and 4 for x and y
AB^2 = 2^2 + 4^2 Expand the right side
AB^2 = 4 + 16 Add the right side
AB^2 = 20 Take the square root of both sides
sqrt(AB^2) = sqrt(20)
Factor 20 = 2*2 *5
Rule: when taking the square root of a number the pairs can take 1 member of the pair outside the root sign and throw the other one a way.
AB = 2 * sqrt(5) One of the roots has been thrown away.
Answer:
x=50
Step-by-step explanation:
since its an isosceles triangle, both of the base angles are going to be the same. Since all of a triangle's angles combined equal 180, and you already have one angle, subtract the 80 from 180.
this leaves you with 100. since there are two angles left, divide 100 by two and thats the value of x
hope this helps!! :)
We need to create an equation in order to solve this problem.
Let x = the smallest number
x+1 = next number
x+2 the following number
x+3
x+4
x+5
x+6
So, we add those.
x+x+1+x+2+x+3+x+4+x+5+x+6=105
7x+21=105
7x = 84
x = 12
So the numbers are
12,13,14,15,16,17,18
