Answer:
B. 10
Step-by-step explanation:
First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)
Let's first label the leg of the second triangle as y.
Then, we can set up this equation
Cross multiplying gives us
84=y^2
So, y=sqrt(84) or 2 sqrt(21).
Now, using the pythagorean theorem, we get
4^2+2sqrt(21)^2=x^2
100=x^2
x=10
Answer:
-5,0,0.56,12%,1/2
Step-by-step explanation:
Answer:
use the formula SA = 6(a + h), where s = side length of the base, a = apothem length, and h = height of the prism.
(1,1) because x + 2y <4
=1 + 2(1)
= 3 which is less than 4
Best answer would be 4 out of 9 (4/9). This is in simplest form. To find probability in this form, find the amount of numbers less than ten (4), then put it over the amount of numbers in the list (9).
Hope this helped :)
