I know easly how to get the angles, but I have no idea how they got x=5??!?!?
what am i suppose to do? like how to work it out.
In isosceles trapezoid ABCD, angle B is 143° and angle C is 9x-8°. What is the value of x and what are the measures of angle A and angle D?
#1
x = 5
Angle A = 143°
Angle D = 37°
thank you =]
