mean = sum/n
mean = (5 + 7 + 7 + 9 + 12 + 16 + 21)/7
mean = 77/7
mean = 11
Tan205° = .466 tan55° = 1.428 tan25° = .466 -tan25° = " so just tan25
55 minus 18 is 37 and then it would be 37,000 and then you just convert it so it is 37% of 100 (the answer is 37%)
The answer would be
~X > 3400~
Hope this helps
Have a great day/night

If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:

(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).
Now, cross multiply and solve for x:
28x+14=30x
<em>*Subtract 28x from both sides to isolate the variable*</em>
14=2x
<em>*Divide both sides by 2*</em>
7=x
Hope this helps!!
