Answer:
measure of angle 3= 41
Step-by-step explanation:
complementary= 90 degrees
angle 3+ angle 4= 90 degrees
90-49=41
The answer is <a is congruent to < d
because you already have <abe = <dbe
You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
