Step-by-step explanation:
14x22=308
<h3>
Answer: 10</h3>
====================================================
Explanation:
The two smaller triangles are proportional, which lets us set up this equation
5/n = n/15
Cross multiplying leads to
5*15 = n*n
n^2 = 75
----------
Apply the pythagorean theorem on the smaller triangle on top, or on the right.
a^2+b^2 = c^2
5^2+n^2 = m^2
25+75 = m^2
100 = m^2
m^2 = 100
m = sqrt(100)
m = 10
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Hope this helped :D
Answer:
assuming the three options are no solutions, one solution and all real numbers, i would say the final option. i forgot what the proper wording is thoough
