Answer:
C) 5√3
Step-by-step explanation:
To find the length of sides CB, use the tan of 30 degrees.
tan 30 = 5/x Simplify
0.577 = 5/x Divide both sides by 0.577
x = 8.66 or 5√3

Answer:
B. 5 hours
Step-by-step explanation:
If the train is going 60mph and we need to find out how long it will be until it is traveling 80mph then we have to do 80-60=20 to figure out how much the speed is changeing. Since every hour the speed increases by 4mph then we have to do how much the train is increasing divided by how much it increases per hour.
20÷4=5
Therefore it will take 5 hours
Answer:
the solution of the equation is: 
Step-by-step explanation:
we are given the expression as 
=
we will use the number line rule for inequalities(first by making the coefficients of x positive then taking the roots on the number line and depending on the sign in the equation we start taking alternate signs and depending on the inequality take the desired region)
we get
.
Answer:
3 7/12
Step-by-step explanation:
Answer:
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
Step-by-step explanation:
we know that
The isosceles trapezoid has
:
Two parallel sides not equal in length called its bases (KL and NM)
Two non-parallel sides equal in length (LM and NK)
so

The perimeter is equal to

substitute the values


3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
