The size of the largest angle in a triangle is 3 times the size of the smallest angle.
The third angle is 10° more than the smallest angle.
Work out the size, in degrees, of each angle in the triangle.
You must show your working (let x be the smallest angle).

34˚, 102˚, 44˚

Step-by-step explanation:

Smallest angle=x

Largest angle= 3x

Third angle= x+10

180=x+(x+10)+3x

180=5x+10

170=5x

x=170/5=34

x=34

3x= 3×34=102

x+10=34+10=44

34, 102, 44

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

center= (-2,0)

radius= sqrt2/2
