What is the angle measure that is a supplementary angle to 21°?

Can (3,5 and square root 34) be sides on a right triangle?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
