X = 6 / tan(67)
x = 2.546
rounded to nearest tenth x = 2.5
In step 2 the 6(1 * x) is supposed to be 6 * 6x.
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
