Answer:
The missing side length is 6.
Step-by-step explanation:
Because the two triangles are similar,
the following equation of ratios is true:
m 4
----- = -----
15 10
Cross-multiplying, we get:
10m = 60, or m = 60/10 = 6
The missing side length is 6.
Answer:
<h2><u><em>
x = 2</em></u></h2>
Step-by-step explanation:
Find the value of x.
5+x=7
x = [?]
5 + x = 7
x = 7 - 5
<u><em>x = 2</em></u>
----------------check
5 + 2 = 7
7 = 7
the answer is good
