When a tangent (top line with the arrow) and a secant (other line) intersect, they form an angle (55°) equal to:
55° = ½ (the larger intercepted arc minus<span> the smaller intercepted arc)
</span>
<span>55° = ½ (170° -x°)
55° = 85° -</span><span>½ x
</span><span>½ x = 30°
x = 60°

1 Simplify n+5+-m-3n+8n+5+−m−3n+8 to n+5-m-3n+8n+5−m−3n+8.
11-2m-(n+5-m-3n+8)11−2m−(n+5−m−3n+8)
2 Collect like terms.
11-2m-((n-3n)+(5+8)-m)11−2m−((n−3n)+(5+8)−m)
3 Simplify (n-3n)+(5+8)-m(n−3n)+(5+8)−m to -2n+13-m−2n+13−m.
11-2m-(-2n+13-m)11−2m−(−2n+13−m)
4 Remove parentheses.
11-2m+2n-13+m11−2m+2n−13+m
5 Collect like terms.
(11-13)+(-2m+m)+2n(11−13)+(−2m+m)+2n
6 Simplify.
-2-m+2n that is the answer plz Mark me brainliest:)

Let x be number of downloads of standard version and y be number of downloads of high quality versions.
The hight quality downloads are twice as the standar downloads. So,
The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,
Substitute 2x for y in the equation and solve the obtained equation for x.
So value of x is 290. Thus downloads of the standard version were 290.
Answer: 290
