Answer:
JK = 24
Step-by-step explanation:
Δ BKJ and Δ BCA are similar triangles and ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
5JK = 120 ( divide both sides by 5 )
JK = 24
Answer:
i think the best estimate is answer b
Step-by-step explanation:
(x-1)^3 / 2 = 27
For equations like this, we want to isolate x in order to get the value of it.
First, let's multiply both sides by 2 to eliminate the fraction.
(x-1)^3 = 27(2)
Now, let's take the cube root of both sides
(x-1) = ∛(27 * 2)
Now, simplify the root
x - 1 = 3∛2
Add both sides by 1
x = 1 + 3∛2
That's your answer.
Have an awesome day! :)
20x2 = 40 in width
180-40= 140
140/2=70
70 inches
