In the figure below, Line segment Eh B is parallel to line segment CD.. In degrees, what is the measure of Angle 4. if the measure of Angle 1 = 50 degrees. and the measure of Angle 3 = 30 degrees.?

Simplify the expression 10/11(22z) + (a+5) -1

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)- 144x+360 what am i doing wrong?

Need 50 will mark brainliest answer. find the lengths of all the sides and the measures of the angles.
