Figure abcd is a rhombus.
if angle 1 = 115° and angle 6 = 40°, what is angle 8?

<B i.e. <1 = 115

<B = <ADC or angle 4 = 115 [Opposite angles of rhombus are equal]

angle 4 = angle 5 = 115[Being vertically opposite angles]

angle 6+ angle 5 = angle 8[Exterior angle of a triangle is equal to sum of two interior opposite angles]

or, 40+115 = angle 8

or, angle 8 = 155

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
